Attributes
and Id
.source§fn on_event(&self, event: &Event<'_>, ctx: Context<'_, S>)
fn on_event(&self, event: &Event<'_>, 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>)

source§fn on_register_dispatch(&self, collector: &Dispatch)
fn on_register_dispatch(&self, collector: &Dispatch)
Performs late initialization when installing this layer as a
Subscriber
. Read moresource§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>)

Id
recorded the given
values

span
recorded that it
follows from the span with the ID follows
.source§fn event_enabled(&self, _event: &Event<'_>, _ctx: Context<'_, S>) -> bool
fn event_enabled(&self, _event: &Event<'_>, _ctx: Context<'_, S>) -> bool

subscriber returned a different ID.
