sourcefn 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

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

Attributes
and Id
. Read more
sourcefn on_record(&self, span: &Id, values: &Record<'_>, ctx: Context<'_, S>)
fn on_record(&self, span: &Id, values: &Record<'_>, ctx: Context<'_, S>)

recorded the given
values
. Read more
sourcefn on_follows_from(&self, span: &Id, follows: &Id, ctx: Context<'_, S>)
fn on_follows_from(&self, span: &Id, follows: &Id, ctx: Context<'_, S>)

recorded that it
follows from the span with the ID follows
. Read more
sourcefn 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.
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_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.
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
