tracing-perfetto-sdk

A tracing-subscriber Layer that emits Perfetto track events via the perfetto-sdk crate.

This bridges the Rust tracing ecosystem with Perfetto's native tracing infrastructure. Spans become duration slices and events become instant events, with full support for debug annotations, source locations, and integration with the Perfetto tracing service.

Quick start

use tracing_subscriber::prelude::*;

tracing_perfetto_sdk::init();
tracing_subscriber::registry()
    .with(tracing_perfetto_sdk::PerfettoLayer::new())
    .init();

let span = tracing::info_span!("my_function", arg = 42);
let _guard = span.enter();
tracing::info!("hello from Perfetto");

Features

• Zero-cost when disabled — category enable check is a single atomic load
• Debug annotations — span and event fields are captured as Perfetto debug annotations
• Source locations — file and line number are attached to every event
• Service integration — works with both in-process tracing and the system tracing service
