Struct sc_tracing::logging::PrefixLayer
source · pub struct PrefixLayer;
Expand description
A Layer
that captures the prefix span (PREFIX_LOG_SPAN
) which is then used by
crate::logging::EventFormat
to prefix the log lines by customizable string.
See the macro sc_cli::prefix_logs_with!
for more details.

source§fn new_span(&self, attrs: &Attributes<'_>, id: &Id, ctx: Context<'_, S>)
fn new_span(&self, attrs: &Attributes<'_>, id: &Id, ctx: Context<'_, S>)

Attributes
and Id
.source§fn 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 moresource§fn 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 moresource§fn on_record(&self, _span: &Id, _values: &Record<'_>, _ctx: Context<'_, S>)
fn on_record(&self, _span: &Id, _values: &Record<'_>, _ctx: Context<'_, S>)
Notifies this layer that a span with the given
Id
recorded the given
values
.source§fn on_follows_from(&self, _span: &Id, _follows: &Id, _ctx: Context<'_, S>)
fn on_follows_from(&self, _span: &Id, _follows: &Id, _ctx: Context<'_, S>)

span
recorded that it
follows from the span with the ID follows
.source§fn on_event(&self, _event: &Event<'_>, _ctx: Context<'_, S>)
fn on_event(&self, _event: &Event<'_>, _ctx: Context<'_, S>)
Notifies this layer that an event has occurred.
source§fn 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.
source§fn 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.
source§fn on_close(&self, _id: Id, _ctx: Context<'_, S>)
fn on_close(&self, _id: Id, _ctx: Context<'_, S>)
Notifies this layer that the span with the given ID has been closed.
source§fn 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.

L: Layer<S>,
Self: Sized,
fn and_then<L>(self, layer: L) -> Layered<L, Self, S>where L: Layer<S>, Self: Sized,
Composes this layer around the given
