§fn on_register_dispatch(&self, subscriber: &Dispatch)
fn on_register_dispatch(&self, subscriber: &Dispatch)

Subscriber
. Read more§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 more§fn enabled(&self, metadata: &Metadata<'_>, ctx: Context<'_, S>) -> bool
fn enabled(&self, metadata: &Metadata<'_>, ctx: Context<'_, S>) -> bool

given metadata
in the current Context
, similarly to
Subscriber::enabled

Attributes
and Id

Notifies this layer that an event has occurred.
§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.
§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.
§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.
§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.
§fn and_then<L>(self, layer: L) -> Layered<L, Self, S>
fn and_then<L>(self, layer: L) -> Layered<L, Self, S>
