Struct TraceContext 

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

A helper to link spans to various actions, namely connection. Sometimes, clients are spawned on separate tasks. This provides a simple way to link traces if a link is preferred in some situations over other types of instrumentation.

Trait Implementations

impl Clone for TraceContext

fn clone(&self) -> TraceContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TraceContext

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

Formats the value using the given formatter.

impl Default for TraceContext

fn default() -> TraceContext

Returns the “default value” for a type.

impl From<NonZero<u64>> for TraceContext

fn from(id: NonZeroU64) -> Self

Converts to this type from the input type.

impl From<Option<NonZero<u64>>> for TraceContext

fn from(id: Option<NonZeroU64>) -> Self

Converts to this type from the input type.

impl PartialEq for TraceContext

fn eq(&self, other: &TraceContext) -> 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 Copy for TraceContext

impl StructuralPartialEq for TraceContext
