Struct TraceContext 

pub struct TraceContext {
    pub request_id: u64,
    pub traceparent: String,
    pub tracestate: String,
}

W3C trace context plus the broker frame request id.

Fields

request_id: u64

Broker frame request id.

traceparent: String

W3C traceparent header value.

tracestate: String

W3C tracestate header value.

Implementations

impl TraceContext

pub fn from_frame(frame: &Frame) -> Self

Capture trace metadata from a broker frame.

pub fn backend_headers(&self) -> Vec<(&'static str, String)>

Return the non-empty W3C headers in backend-forwarding order.

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.
