Implementations

impl TraceEvent

pub fn kind(&self) -> &'static str

The type tag serde writes for this variant. This is the single source of truth for event-kind strings — consumers (e.g. the trace viewer) match on the enum and read the kind from here rather than re-deriving tag strings by hand. The match is exhaustive on purpose: a new variant fails to compile here until it is given a kind.

Trait Implementations

impl Clone for TraceEvent

fn clone(&self) -> TraceEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TraceEvent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TraceEvent

fn deserialize<__D>( __deserializer: __D, ) -> Result<TraceEvent, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TraceEvent

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for TraceEvent

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
