Overview

tracing is a framework for instrumenting Rust programs to collect structured, event-based diagnostic information. This crate provides the #[instrument] attribute for automatically instrumenting functions using tracing.

Note that this macro is also re-exported by the main tracing crate.

Usage

First, add this to your Cargo.toml:

[dependencies]
tracing-attributes = "0.1.9"

Compiler support: requires rustc 1.39+

This crate provides the #[instrument] attribute for instrumenting a function with a tracing span. For example:

use tracing_attributes::instrument;

#[instrument]
pub fn my_function(my_arg: usize) {
    // ...
}
