Struct ByName 

pub struct ByName;

Group spans/events by their “name”.

For spans, this is the string passed as the first argument to the various span tracing macros. For events, this is usually the source file and line number where the event was created.

Trait Implementations

impl Clone for ByName

fn clone(&self) -> ByName

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ByName

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

Formats the value using the given formatter.

impl Default for ByName

fn default() -> ByName

Returns the “default value” for a type.

impl EventGroup for ByName

type Id = &'static str

The type of the timing event group.

fn group(&self, e: &Event<'_>) -> Self::Id

Extract the group for this event.

impl PartialEq for ByName

fn eq(&self, other: &ByName) -> 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 SpanGroup for ByName

type Id = &'static str

The type of the timing span group.

fn group(&self, a: &Attributes<'_>) -> Self::Id

Extract the group for this span’s attributes.

impl Copy for ByName
