pub struct BunyanFormattingLayer<W: for<'a> MakeWriter<'a> + 'static> { /* private fields */ }
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
sourceimpl<W: for<'a> MakeWriter<'a> + 'static> BunyanFormattingLayer<W>
impl<W: for<'a> MakeWriter<'a> + 'static> BunyanFormattingLayer<W>
sourcepub fn new(name: String, make_writer: W) -> Self
pub fn new(name: String, make_writer: W) -> Self
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());
pub fn with_default_fields(
name: String,
make_writer: W,
default_fields: HashMap<String, Value>
) -> Self

sourcefn on_event(&self, event: &Event<'_>, ctx: Context<'_, S>)
fn on_event(&self, event: &Event<'_>, ctx: Context<'_, S>)

sourcefn on_register_dispatch(&self, collector: &Dispatch)
fn on_register_dispatch(&self, collector: &Dispatch)
Performs late initialization when installing this layer as a
Subscriber
. Read moresourcefn register_callsite(&self, metadata: &'static Metadata<'static>) -> Interest
fn register_callsite(&self, metadata: &'static Metadata<'static>) -> Interest
Registers a new callsite with this layer, returning whether or not
the layer is interested in being notified about the callsite, similarly
to
Subscriber::register_callsite
. Read moresourcefn enabled(&self, metadata: &Metadata<'_>, ctx: Context<'_, S>) -> bool
fn enabled(&self, metadata: &Metadata<'_>, ctx: Context<'_, S>) -> bool
Returns
true
if this layer is interested in a span or event with the
given metadata
in the current Context
, similarly to
Subscriber::enabled
. Read moresourcefn on_follows_from(&self, _span: &Id, _follows: &Id, _ctx: Context<'_, S>)
fn on_follows_from(&self, _span: &Id, _follows: &Id, _ctx: Context<'_, S>)
Notifies this layer that a span with the ID
span
recorded that it
follows from the span with the ID follows

fn event_enabled(&self, _event: &Event<'_>, _ctx: Context<'_, S>) -> bool
sourcefn on_enter(&self, _id: &Id, _ctx: Context<'_, S>)
fn on_enter(&self, _id: &Id, _ctx: Context<'_, S>)
Notifies this layer that a span with the given ID was entered.
sourcefn on_exit(&self, _id: &Id, _ctx: Context<'_, S>)
fn on_exit(&self, _id: &Id, _ctx: Context<'_, S>)
Notifies this layer that the span with the given ID was exited.
sourcefn on_id_change(&self, _old: &Id, _new: &Id, _ctx: Context<'_, S>)
fn on_id_change(&self, _old: &Id, _new: &Id, _ctx: Context<'_, S>)
Notifies this layer that a span ID has been cloned, and that the
subscriber returned a different ID. Read more
