# Overview

tracing-chrome is a Layer for [tracing-subscriber](https://crates.io/crates/tracing-subscriber) that outputs traces in Chrome's trace viewer format that can be viewed with `chrome://tracing` or [ui.perfetto.dev](https://ui.perfetto.dev).

# Usage

Add this near the beginning of `main`:

```rust

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](https://ui.perfetto.dev) (or `chrome://tracing`) and take a look at your pretty trace.
