{ /* private fields */ }

Implementations

Set the file to which to output the trace.

Defaults to “./trace-{unix epoch time}.json”

Include arguments in each trace entry.

Defaults to false.

Includes the arguments used when creating a span/event in the “args” section of the trace entry.

Include file+line with each trace entry.

Defaults to true.

This can add quite a bit of data to the output so turning it off might be helpful when collecting larger traces.

Sets the style used when recording trace events. See TraceStyle for details.

Allows supplying a function that derives a name from an Event or Span. The result is used as the “name” field on trace entries.

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

let (chrome_layer, _guard) = ChromeLayerBuilder::new().name_fn(Box::new(|event_or_span| {
    match event_or_span {
        EventOrSpan::Event(ev) => { ev.metadata().name().into() },
        EventOrSpan::Span(_s) => { "span".into() },
    }
})).build();
tracing_subscriber::registry().with(chrome_layer).init()

Allows supplying a function that derives a category from an Event or Span. The result is used as the “cat” field on trace entries.

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

let (chrome_layer, _guard) = ChromeLayerBuilder::new().category_fn(Box::new(|_| {
    "my_module".into()
})).build();
tracing_subscriber::registry().with(chrome_layer).init()
