# 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.
