Struct metrics_tracing_context::MetricsLayer [−][src]
pub struct MetricsLayer<S> { /* fields omitted */ }
Expand description
MetricsLayer
is a tracing_subscriber::Layer
that captures the span
fields and allows them to be later on used as metrics labels.

[src]fn new_span(&self, attrs: &Attributes<'_>, id: &Id, cx: Context<'_, S>)
[src]
fn new_span(&self, attrs: &Attributes<'_>, id: &Id, cx: Context<'_, S>)

[src]
fn register_callsite(&self, metadata: &'static Metadata<'static>) -> Interest
[src]
fn register_callsite(&self, metadata: &'static Metadata<'static>) -> Interest
[src]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

fn enabled(&self, metadata: &Metadata<'_>, ctx: Context<'_, S>) -> bool
[src]
fn enabled(&self, metadata: &Metadata<'_>, ctx: Context<'_, S>) -> bool
[src]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 more

[src]
fn on_follows_from(&self, _span: &Id, _follows: &Id, _ctx: Context<'_, S>)
[src]Notifies this layer that a span with the ID span
recorded that it
follows from the span with the ID follows
. Read more
fn on_event(&self, _event: &Event<'_>, _ctx: Context<'_, S>)
[src]
fn on_event(&self, _event: &Event<'_>, _ctx: Context<'_, S>)

fn on_enter(&self, _id: &Id, _ctx: Context<'_, S>)
[src]
fn on_enter(&self, _id: &Id, _ctx: Context<'_, S>)
[src]Notifies this layer that a span with the given ID was entered.
fn on_exit(&self, _id: &Id, _ctx: Context<'_, S>)
[src]
fn on_exit(&self, _id: &Id, _ctx: Context<'_, S>)
[src]Notifies this layer that the span with the given ID was exited.
fn on_close(&self, _id: Id, _ctx: Context<'_, S>)
[src]
fn on_close(&self, _id: Id, _ctx: Context<'_, S>)
[src]Notifies this layer that the span with the given ID has been closed.
fn on_id_change(&self, _old: &Id, _new: &Id, _ctx: Context<'_, S>)
[src]
fn on_id_change(&self, _old: &Id, _new: &Id, _ctx: Context<'_, S>)
[src]Notifies this layer that a span ID has been cloned, and that the subscriber returned a different ID. Read more
fn and_then<L>(self, layer: L) -> Layered<L, Self, S> where
L: Layer<S>,
[src]
fn and_then<L>(self, layer: L) -> Layered<L, Self, S> where
L: Layer<S>,
