| //! [QUIC event definitions], and [HTTP/3 and QPACK event definitions]. |
| //! The crate provides a qlog data model that can be used for traces with |
| //! events. It supports serialization and deserialization but defers logging IO |
| //! choices to applications. |
| //! |
| //! Serialization operates in either a [buffered mode] or a [streaming mode]. |
| //! |
| //! The crate uses Serde for conversion between Rust and JSON. |

| //! [streaming mode]: #streaming-traces-with-json-seq |
| //! |
| //! Overview |
| //! --------------- |
| //! qlog is a hierarchical logging format, with a rough structure of: |
| //! |
| //! * Log |
| //! * Trace(s) |
| //! * Event(s) |
| //! |
| //! In practice, a single QUIC connection maps to a single Trace file with one |
| //! or more Events. Applications can decide whether to combine Traces from |
| //! different connections into the same Log. |
| //! |
| //! ## Buffered Traces with standard JSON |
| //! |
| //! A [`Trace`] is a single JSON object. It contains metadata such as the |
| //! [`VantagePoint`] of capture and the [`Configuration`], and protocol event |
| //! data in the [`Event`] array. |
| //! |
| //! JSON Traces allow applications to appends events to them before eventually |
| //! being serialized as a complete JSON object. |
| //! |
| //! ### Creating a Trace |
| //! |
| //! ``` |
| //! let mut trace = qlog::Trace::new( |
| //! qlog::VantagePoint { |
| //! name: Some("Example client".to_string()), |
| //! ty: qlog::VantagePointType::Client, |
| //! flow: None, |
| //! }, |
| //! Some("Example qlog trace".to_string()), |
| //! Some("Example qlog trace description".to_string()), |
| //! Some(qlog::Configuration { |
| //! time_offset: Some(0.0), |
| //! original_uris: None, |
| //! }), |
| //! None, |
| //! ); |
| //! ``` |
| //! |
| //! ### Adding events to a Trace |
| //! |
| //! Qlog [`Event`] objects are added to [`qlog::Trace.events`]. |
| //! |
| //! The following example demonstrates how to log a qlog QUIC `packet_sent` |
| //! event containing a single Crypto frame. It constructs the necessary elements |
| //! of the [`Event`], then appends it to the trace with [`push_event()`]. |
| //! |
| //! ``` |
| //! # let mut trace = qlog::Trace::new ( |
| //! # qlog::VantagePoint { |
| //! # name: Some("Example client".to_string()), |
| //! # ty: qlog::VantagePointType::Client, |
| //! # flow: None, |
| //! # }, |
| //! # Some("Example qlog trace".to_string()), |
| //! # Some("Example qlog trace description".to_string()), |
| //! # Some(qlog::Configuration { |
| //! # time_offset: Some(0.0), |
| //! # original_uris: None, |
| //! # }), |
| //! # None |
| //! # ); |
| //! |
| //! let scid = [0x7e, 0x37, 0xe4, 0xdc, 0xc6, 0x68, 0x2d, 0xa8]; |
| //! let dcid = [0x36, 0xce, 0x10, 0x4e, 0xee, 0x50, 0x10, 0x1c]; |
| //! |
| //! let pkt_hdr = qlog::events::quic::PacketHeader::new( |
| //! qlog::events::quic::PacketType::Initial, |
| //! Some(0), // packet_number |
| //! None, // flags |
| //! None, // token |
| //! None, // length |
| //! Some(0x00000001), // version |
| //! Some(&scid), |
| //! Some(&dcid), |
| //! ); |
| //! |
| //! let frames = vec![qlog::events::quic::QuicFrame::Crypto { |
| //! offset: 0, |
| //! length: 0, |
| //! }]; |
| //! |
| //! let raw = qlog::events::RawInfo { |
| //! length: Some(1251), |
| //! payload_length: Some(1224), |
| //! data: None, |
| //! }; |
| //! |
| //! let event_data = |
| //! qlog::events::EventData::PacketSent(qlog::events::quic::PacketSent { |
| //! header: pkt_hdr, |
| //! frames: Some(frames.into()), |
| //! is_coalesced: None, |
| //! retry_token: None, |
| //! stateless_reset_token: None, |
| //! supported_versions: None, |
| //! raw: Some(raw), |
| //! datagram_id: None, |
| //! send_at_time: None, |
| //! trigger: None, |
| //! }); |
| //! |
| //! trace.push_event(qlog::events::Event::with_time(0.0, event_data)); |
| //! ``` |
| //! |
| //! ### Serializing |
| //! |
| //! The qlog crate has only been tested with `serde_json`, however |
| //! other serializer targets might work. |
| //! |
| //! For example, serializing the trace created above: |
| //! |
| //! ``` |
| //! # let mut trace = qlog::Trace::new ( |
| //! # qlog::VantagePoint { |
| //! # name: Some("Example client".to_string()), |
| //! # ty: qlog::VantagePointType::Client, |
| //! # flow: None, |
| //! # }, |
| //! # Some("Example qlog trace".to_string()), |
| //! # Some("Example qlog trace description".to_string()), |
| //! # Some(qlog::Configuration { |
| //! # time_offset: Some(0.0), |
| //! # original_uris: None, |
| //! # }), |
| //! # None |
| //! # ); |
| //! serde_json::to_string_pretty(&trace).unwrap(); |
| //! ``` |
| //! |
| //! which would generate the following: |
| //! |
| //! ```ignore |
| //! { |
| //! "vantage_point": { |
| //! "name": "Example client", |
| //! "type": "client" |
| //! }, |
| //! "title": "Example qlog trace", |
| //! "description": "Example qlog trace description", |
| //! "configuration": { |
| //! "time_offset": 0.0 |
| //! }, |
| //! "events": [ |
| //! { |
| //! "time": 0.0, |
| //! "name": "transport:packet_sent", |
| //! "data": { |
| //! "header": { |
| //! "packet_type": "initial", |
| //! "packet_number": 0, |
| //! "version": "1", |
| //! "scil": 8, |
| //! "dcil": 8, |
| //! "scid": "7e37e4dcc6682da8", |
| //! "dcid": "36ce104eee50101c" |
| //! }, |
| //! "raw": { |
| //! "length": 1251, |
| //! "payload_length": 1224 |
| //! }, |
| //! "frames": [ |
| //! { |
| //! "frame_type": "crypto", |
| //! "offset": 0, |
| //! "length": 0 |
| //! } |
| //! ] |
| //! } |
| //! } |
| //! ] |
| //! } |
| //! ``` |
| //! |
| //! ## Streaming Traces with JSON-SEQ |
| //! |
| //! To help support streaming serialization of qlogs, |
| //! draft-ietf-quic-qlog-main-schema-01 introduced support for RFC 7464 JSON |
| //! Text Sequences (JSON-SEQ). The qlog crate supports this format and provides |
| //! utilities that aid streaming. |
| //! |
| //! A [`TraceSeq`] contains metadata such as the [`VantagePoint`] of capture and |
| //! the [`Configuration`]. However, protocol event data is handled as separate |
| //! lines containing a record separator character, a serialized [`Event`], and a |
| //! newline. |
| //! |
| //! ### Creating a TraceSeq |
| //! |
| //! ``` |
| //! let mut trace = qlog::TraceSeq::new( |
| //! qlog::VantagePoint { |
| //! name: Some("Example client".to_string()), |
| //! ty: qlog::VantagePointType::Client, |
| //! flow: None, |
| //! }, |
| //! Some("Example qlog trace".to_string()), |
| //! Some("Example qlog trace description".to_string()), |
| //! Some(qlog::Configuration { |
| //! time_offset: Some(0.0), |
| //! original_uris: None, |
| //! }), |
| //! None, |
| //! ); |
| //! ``` |
| //! |
| //! Create an object with the [`Write`] trait: |
| //! |
| //! ``` |
| //! let mut file = std::fs::File::create("foo.sqlog").unwrap(); |
| //! ``` |
| //! |
| //! Create a [`QlogStreamer`] and start serialization to foo.sqlog |
| //! using [`start_log()`]: |
| //! |
| //! ``` |
| //! # let mut trace = qlog::TraceSeq::new( |
| //! # qlog::VantagePoint { |
| //! # name: Some("Example client".to_string()), |
| //! # ty: qlog::VantagePointType::Client, |
| //! # flow: None, |
| //! # }, |
| //! # Some("Example qlog trace".to_string()), |
| //! # Some("Example qlog trace description".to_string()), |
| //! # Some(qlog::Configuration { |
| //! # time_offset: Some(0.0), |
| //! # original_uris: None, |
| //! # }), |
| //! # None, |
| //! # ); |
| //! # let mut file = std::fs::File::create("foo.sqlog").unwrap(); |
| //! let mut streamer = qlog::streamer::QlogStreamer::new( |
| //! qlog::QLOG_VERSION.to_string(), |
| //! Some("Example qlog".to_string()), |
| //! Some("Example qlog description".to_string()), |
| //! None, |
| //! std::time::Instant::now(), |
| //! trace, |
| //! qlog::events::EventImportance::Base, |
| //! Box::new(file), |
| //! ); |
| //! |
| //! streamer.start_log().ok(); |
| //! ``` |
| //! |
| //! ### Adding events |
| //! |
| //! Once logging has started you can stream events. Events |
| //! are written in one step using one of [`add_event()`], |
| //! [`add_event_with_instant()`], [`add_event_now()`], |
| //! [`add_event_data_with_instant()`], or [`add_event_data_now()`] : |
| //! |
| //! ``` |
| //! # let mut trace = qlog::TraceSeq::new( |
| //! # qlog::VantagePoint { |
| //! # name: Some("Example client".to_string()), |
| //! # ty: qlog::VantagePointType::Client, |
| //! # flow: None, |
| //! # }, |
| //! # Some("Example qlog trace".to_string()), |
| //! # Some("Example qlog trace description".to_string()), |
| //! # Some(qlog::Configuration { |
| //! # time_offset: Some(0.0), |
| //! # original_uris: None, |
| //! # }), |
| //! # None, |
| //! # ); |
| //! # let mut file = std::fs::File::create("foo.qlog").unwrap(); |
| //! # let mut streamer = qlog::streamer::QlogStreamer::new( |
| //! # qlog::QLOG_VERSION.to_string(), |
| //! # Some("Example qlog".to_string()), |
| //! # Some("Example qlog description".to_string()), |
| //! # None, |
| //! # std::time::Instant::now(), |
| //! # trace, |
| //! # qlog::events::EventImportance::Base, |
| //! # Box::new(file), |
| //! # ); |
| //! |
| //! let scid = [0x7e, 0x37, 0xe4, 0xdc, 0xc6, 0x68, 0x2d, 0xa8]; |
| //! let dcid = [0x36, 0xce, 0x10, 0x4e, 0xee, 0x50, 0x10, 0x1c]; |
| //! |
| //! let pkt_hdr = qlog::events::quic::PacketHeader::with_type( |
| //! qlog::events::quic::PacketType::OneRtt, |
| //! Some(0), |
| //! Some(0x00000001), |
| //! Some(&scid), |
| //! Some(&dcid), |
| //! ); |
| //! |
| //! let ping = qlog::events::quic::QuicFrame::Ping { |
| //! length: None, |
| //! payload_length: None, |
| //! }; |
| //! let padding = qlog::events::quic::QuicFrame::Padding { |
| //! length: None, |
| //! payload_length: 1234, |
| //! }; |
| //! |
| //! let event_data = |
| //! qlog::events::EventData::PacketSent(qlog::events::quic::PacketSent { |
| //! header: pkt_hdr, |
| //! frames: Some(vec![ping, padding].into()), |
| //! is_coalesced: None, |
| //! retry_token: None, |
| //! stateless_reset_token: None, |
| //! supported_versions: None, |
| //! raw: None, |
| //! datagram_id: None, |
| //! send_at_time: None, |
| //! trigger: None, |
| //! }); |
| //! |
| //! let event = qlog::events::Event::with_time(0.0, event_data); |
| //! |
| //! streamer.add_event(event).ok(); |
| //! ``` |
| //! |
| //! Once all events have been written, the log |
| //! can be finalized with [`finish_log()`]: |
| //! |
| //! ``` |
| //! # let mut trace = qlog::TraceSeq::new( |
| //! # qlog::VantagePoint { |
| //! # name: Some("Example client".to_string()), |
| //! # ty: qlog::VantagePointType::Client, |
| //! # flow: None, |
| //! # }, |
| //! # Some("Example qlog trace".to_string()), |
| //! # Some("Example qlog trace description".to_string()), |
| //! # Some(qlog::Configuration { |
| //! # time_offset: Some(0.0), |
| //! # original_uris: None, |
| //! # }), |
| //! # None, |
| //! # ); |
| //! # let mut file = std::fs::File::create("foo.qlog").unwrap(); |
| //! # let mut streamer = qlog::streamer::QlogStreamer::new( |
| //! # qlog::QLOG_VERSION.to_string(), |
| //! # Some("Example qlog".to_string()), |
| //! # Some("Example qlog description".to_string()), |
| //! # None, |
| //! # std::time::Instant::now(), |
| //! # trace, |
| //! # qlog::events::EventImportance::Base, |
| //! # Box::new(file), |
| //! # ); |
| //! streamer.finish_log().ok(); |
| //! ``` |
| //! |
| //! ### Serializing |
| //! |
| //! Serialization to JSON occurs as methods on the [`QlogStreamer`] |
| //! are called. No additional steps are required. |
