Struct `Kind`

pub struct Kind(/* private field */);

Indicates whether the callsite is a span or event.

Implementations

`impl Kind`

const EVENT: Kind = _;

Event callsite

const SPAN: Kind = _;

Span callsite

const HINT: Kind = _;

enabled! callsite. [Subscriber]crate::subscriber::Subscribers can assume this Kind means they will never receive a full event with this Metadata.

fn is_span(&self) -> bool

Return true if the callsite kind is Span

fn is_event(&self) -> bool

Return true if the callsite kind is Event

fn is_hint(&self) -> bool

Return true if the callsite kind is Hint

const fn hint(self) -> Self

Sets that this Kind is a hint.

This can be called on SPAN and EVENT kinds to construct a hint callsite that also counts as a span or event.
