Struct OperationContext 

pub struct OperationContext { /* private fields */ }

Tracks observability context for a single operation.

Mirrors Go’s observability.OperationContext.

Implementations

impl OperationContext

pub fn new( service: impl Into<String>, operation: impl Into<String>, request_id: impl Into<String>, user_id: impl Into<String>, ) -> Self

Create a new operation context.

pub fn with_metrics(self, metrics: Arc<MetricsHandle>) -> Self

Attach a metrics handle to this context.

pub fn service_name(&self) -> &str

Name of the service performing the operation.

pub fn operation_name(&self) -> &str

Name of the operation being performed.

pub fn request_id(&self) -> &str

Unique request identifier for correlation.

pub fn user_id(&self) -> &str

Identifier of the user initiating the request.

This is retained for caller-side correlation and is not emitted to spans by default to avoid leaking user identifiers into telemetry backends.

pub fn start_span(&self, name: &str) -> Span

Create a tracing span for a sub-operation.

pub fn end_operation(&self, status: &str, error: Option<&AppError>)

Record the end of the operation with status and optional error.

pub fn elapsed(&self) -> Duration

Time elapsed since the context was created.
