Struct tracing_core::metadata::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 recieve 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) -> 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.

Trait Implementations

impl Clone for Kind

fn clone(&self) -> Kind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Kind

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

Formats the value using the given formatter.

impl PartialEq for Kind

fn eq(&self, other: &Kind) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
