Struct tracing_bunyan_formatter::BunyanFormattingLayer [−][src]
pub struct BunyanFormattingLayer<W: for<'a> MakeWriter<'a> + 'static> { /* fields omitted */ }
Expand description
This layer is exclusively concerned with formatting information using the Bunyan format.
It relies on the upstream JsonStorageLayer
to get access to the fields attached to
each span.
Implementations
Create a new BunyanFormattingLayer
.
You have to specify:
- a
name
, which will be attached to all formatted records according to the Bunyan format; - a
make_writer
, which will be used to get aWrite
instance to write formatted records to.
Using stdout
use tracing_bunyan_formatter::BunyanFormattingLayer;
let formatting_layer = BunyanFormattingLayer::new("tracing_example".into(), std::io::stdout);
If you prefer, you can use closure syntax:
use tracing_bunyan_formatter::BunyanFormattingLayer;
let formatting_layer = BunyanFormattingLayer::new("tracing_example".into(), || std::io::stdout());
