Struct Or

pub struct Or<A, B, S> { /* private fields */ }

Available on crate features registry and std only.

Combines two Filters so that spans and events are enabled if either filter returns true.

This type is typically returned by the FilterExt::or method. See that method’s documentation for details.

Trait Implementations

impl<A, B, S> Clone for Or<A, B, S>

where A: Clone, B: Clone,

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<A, B, S> Debug for Or<A, B, S>

where A: Debug, B: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<A, B, S> Filter<S> for Or<A, B, S>

where A: Filter<S>, B: Filter<S>,

fn enabled(&self, meta: &Metadata<'_>, cx: &Context<'_, S>) -> bool

Returns true if this subscriber is interested in a span or event with the given Metadata in the current Context, similarly to Collect::enabled.

fn callsite_enabled(&self, meta: &'static Metadata<'static>) -> Interest

Returns an Interest indicating whether this subscriber will always, sometimes, or never be interested in the given Metadata.

fn max_level_hint(&self) -> Option<LevelFilter>

Returns an optional hint of the highest verbosity level that this Filter will enable.

fn event_enabled(&self, event: &Event<'_>, cx: &Context<'_, S>) -> bool

Called before the filtered subscribers’ on_event, to determine if on_event should be called.

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

Notifies this filter that a new span was constructed with the given Attributes and Id.

fn on_record(&self, id: &Id, values: &Record<'_>, ctx: Context<'_, S>)

Notifies this filter that a span with the given Id recorded the given values.

fn on_enter(&self, id: &Id, ctx: Context<'_, S>)

Notifies this filter that a span with the given ID was entered.

fn on_exit(&self, id: &Id, ctx: Context<'_, S>)

Notifies this filter that a span with the given ID was exited.

fn on_close(&self, id: Id, ctx: Context<'_, S>)

Notifies this filter that a span with the given ID has been closed.
