pub struct TraceContext {
    pub traceparent: String,
    pub tracestate: Option<String>,
}

W3C trace context linking telemetry across process boundaries.

Fields

traceparent: String

W3C traceparent header: version, trace ID, parent span ID, and trace flags.

tracestate: Option<String>

Optional W3C tracestate header carrying vendor-specific trace state.

Implementations

impl TraceContext

pub fn from_meta(meta: &Meta) -> Option<Self>

Reads the trace context a caller attached to MCP request metadata via to_meta, if any.

pub fn to_meta(&self) -> Meta

Attaches the trace context to MCP request metadata.

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

impl Eq for TraceContext

impl JsonSchema for TraceContext

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema
