Struct TraceContext 

#[non_exhaustive]
pub struct TraceContext {
    pub traceparent: Option<String>,
    pub tracestate: Option<String>,
}

W3C Trace Context headers propagated to and from the GitHub Copilot CLI.

traceparent carries the trace and parent-span identifiers; tracestate carries vendor-specific extensions. Either field may be None when the caller has nothing to propagate; in that case the corresponding wire field is omitted.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

traceparent: Option<String>

traceparent HTTP header value.

tracestate: Option<String>

tracestate HTTP header value.

Implementations

impl TraceContext

pub fn new() -> Self

Construct an empty TraceContext; both fields default to unset (the SDK skips trace-context injection on the wire).

pub fn from_traceparent(traceparent: impl Into<String>) -> Self

Construct a TraceContext from a traceparent header value, with no tracestate.

Equivalent to TraceContext::new().with_traceparent(value); kept for ergonomics in the common single-header case.

pub fn with_traceparent(self, traceparent: impl Into<String>) -> Self

Set or replace the traceparent header value, returning self for chaining.

pub fn with_tracestate(self, tracestate: impl Into<String>) -> Self

Set or replace the tracestate header value, returning self for chaining.

pub fn is_empty(&self) -> bool

Returns true when neither traceparent nor tracestate is set.

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 Eq for TraceContext

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.
