Learn how to set up highlight.io tracing with the tracing crate.

1

Set up your highlight.io SDK.

First, make sure you've followed the backend getting started guide.

2

Add the tracing crate to your project.

The tracing crate allows you and your dependencies to record traces that will be automatically captured by the highlight.io SDK.

[dependencies] tracing = "0.1"

3

Record a trace.

Use the tracing crate to create spans and events. You can read more about this on the docs.rs page of the tracing crate.

use tracing::{event, span, Level}; // ... let span = span!(Level::INFO, "my_span"); let _guard = span.enter(); event!(Level::DEBUG, "something happened inside my_span");

4

Verify your backend traces are being recorded.

Visit the highlight traces portal and check that backend traces are coming in.
