fidl library

A wrapper type for optional values that may also be null. This generic class can be used in argument lists for optional arguments. When called, the argument state will be one of:

Proxy<T>

Sends messages to a remote implementation of T

ProxyController<T>

The control plane for an interface proxy.

ProxyError

The object that ProxyController<T>.error completes with when there is an error.

Service

Representation of a service that all T implementations should extend from.

ServiceData<T>

Exposes the ability to get a hold of the service runtime name and bindings.

Some<T>

A value wrapped in Some can be assigned to an OptionalNullable to convey the value should be used instead of a default.

UnknownEvent

Event used when an unknown, flexible event is received.

UnknownRawData

UnknownRawData is a container for the raw bytes and handles of an unknown envelope. It has an associate UnknownRawDataType that allows encoding/ decoding instances of this class.

UnknownRawDataType

This encodes/decodes the UnknowRawData assuming it is in an envelope, i.e. payload bytes followed directly by handles.

Functions

align(int size) int

decodeMessage<T>(IncomingMessage message, int inlineSize, MemberType typ) T

Decodes a FIDL message that contains a single parameter.

decodeMessageWithCallback<A>(IncomingMessage message, int inlineSize, A f(Decoder decoder)) A

Decodes a FIDL message with multiple parameters. The callback parameter provides a decoder that is initialized on the provided Message, which callers can use to decode specific types. The return result of the callback (e.g. the decoded parameters, wrapped in a containing class/struct) is returned as the result of the function. This functionality (decoding multiple parameters) is implemented using a callback because returning a list would be insufficient: the list would be of type List, whereas we want to retain concrete types of each decoded parameter. The only way to accomplish this in Dart is to pass in a function that collects these multiple values into a bespoke, properly typed class.

encodeMessage<T>(Encoder encoder, int inlineSize, MemberType typ, T value) void

Encodes a FIDL message that contains a single parameter.

encodeMessageWithCallback(Encoder encoder, int inlineSize, dynamic f()) void

Encodes a FIDL message with multiple parameters. The callback parameter provides a decoder that is initialized on the provided Message, which callers can use to decode specific types. This functionality (encoding multiple parameters) is implemented using a callback because each call to MemberType.encode() must pass in a concrete type, rather than an element popped from a List.

envelopeSize(WireFormat wireFormat) int

handleException(String name, dynamic exception, void close()) void

Calls close and prints the exception.

performCtrlWithExceptionHandling(String name, dynamic ctrl, String type, void additionalErrorListener(Object error, StackTrace stackTrace), void work()) void

Wraps work with common try/catch behaviour and timeline events.

performWithExceptionHandling(String name, void work(), void close()) void

Wraps work with common try/catch behaviour and timeline events.

strictnessFromFlags(int dynamicFlags) CallStrictness

Extract the CallStrictness from the dynamic flags byte of the message header.

strictnessToFlags(CallStrictness strictness) int

Convert CallStrictness to a byte that can be inserted into the dynamic flags portion of a message.

Enums

CallStrictness

EnvelopeContentLocation

EnvelopePresence

FidlErrorCode

InterfaceState

The different states that an AsyncBinding or AsyncProxy can be in.

TransportErr

FIDL internal transport error type, used for unknown interactions.
