Crate tracing_chrome

tracing-chrome

Overview

tracing-chrome is a Layer for tracing-subscriber that outputs traces in Chrome’s trace viewer format that can be viewed with chrome://tracing or ui.perfetto.dev.

Usage

Add this near the beginning of main:

use tracing_chrome::ChromeLayerBuilder;
use tracing_subscriber::{registry::Registry, prelude::*};

let (chrome_layer, _guard) = ChromeLayerBuilder::new().build();
tracing_subscriber::registry().with(chrome_layer).init();

When _guard is dropped, your trace will be in a file like trace-1668480819035032.json.

Open that file with ui.perfetto.dev (or chrome://tracing) and take a look at your pretty trace.
