Struct Kind 

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

Indicates whether the callsite is a span or event.

Implementations

impl Kind

pub const EVENT: Kind

Event callsite

pub const SPAN: Kind

Span callsite

pub const HINT: Kind

enabled! callsite. Subscribers can assume this Kind means they will never receive a full event with this Metadata.

pub fn is_span(&self) -> bool

Return true if the callsite kind is Span

pub fn is_event(&self) -> bool

Return true if the callsite kind is Event

pub fn is_hint(&self) -> bool

Return true if the callsite kind is Hint

pub const fn hint(self) -> Kind

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.
