Struct OperationSpan 

pub struct OperationSpan { /* private fields */ }

Explicitly pass context() across execution boundaries; no ambient span is entered across an async suspension. Completing a span emits one event.

Implementations

impl OperationSpan

pub fn finish_observed( self, outcome: Outcome, category: Option<FailureCategory>, )

Timestamp evidence when the owner obtains it, before asynchronous delivery. A later status projection must retain this instant, never replace it.

pub fn with_attempt(self, attempt: u32) -> Self

Number an existing transport attempt; this never authorizes a retry.

pub fn record_start(&self)

Emit one bounded dispatch entry before work begins.

pub fn with_error_code(self, code: PublicErrorCode) -> Self

Attach only a closed, already-public code; no message or detail is accepted.

pub fn with_operation_id(self, operation_id: Uuid) -> Self

pub fn context(&self) -> CorrelationContext

pub fn finish(self, outcome: Outcome, failure_category: Option<FailureCategory>)

pub fn finish_with_evidence( self, outcome: Outcome, failure_category: Option<FailureCategory>, evidence: &[Measurement], )
