Struct tracing_core::metadata::Kind

source · [−]

pub struct Kind(_);

Expand description

Indicates whether the callsite is a span or event.

Implementations

source

impl Kind

source

pub const EVENT: Kind

Event callsite

source

pub const SPAN: Kind

Span callsite

source

pub const HINT: Kind

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

source

pub fn is_span(&self) -> bool

Return true if the callsite kind is Span

source

pub fn is_event(&self) -> bool

Return true if the callsite kind is Event

source

pub fn is_hint(&self) -> bool

Return true if the callsite kind is Hint

source

pub 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.
