ChromeLayerBuilder

✓ use tracing_chrome::ChromeLayerBuilder;

Initializes a Chrome tracing layer and logs an info event.

use tracing_chrome::ChromeLayerBuilder; use tracing_subscriber::prelude::*; fn main() { let (chrome_layer, _guard) = ChromeLayerBuilder::new().build(); tracing_subscriber::registry().with(chrome_layer).init(); tracing::info!("Hello, Chrome trace!"); }

Debug

Known issues

gotchaThe guard must be kept alive for the duration of tracing; dropping it stops the trace.

fix

Store the guard in a variable with a long enough lifetime, e.g., let _guard = ...;

affects: >=0.7.0
