Crates/Tracing

How to Add tracing to Async Rust Applications Add tracing to async Rust applications by including the `tracing` crate in `Cargo.toml` and using the `#[tracing::instrument]` attribute on async functions to automatically log entry, exit, and duration. How to Use Spans for Request Tracing in Rust Use the tracing crate and instrument macro to create spans for request tracing in Rust. How to Use Structured Logging in Rust with tracing Initialize the tracing crate with a subscriber to log structured events as key-value pairs in Rust. How to Use the tracing Crate in Rust Add the tracing crate to Cargo.toml and initialize a subscriber to enable structured logging and diagnostics in Rust. How to use tracing crate in Rust logging and diagnostics Initialize the tracing subscriber and use macros or attributes to log events for diagnostics. How to Use tracing-subscriber for Log Output Initialize the logger by calling `rustc_log::init_logger` with a configuration derived from an environment variable like `LOG`. This sets up `tracing-subscriber` to handle log output based on the filter rules you define.
