Module telemetry_headers 

Headers that carry a caller’s ray ID and W3C trace context into an actor, shared by every Rust peer of the actor HTTP surface: the runtime that reads them and the clients that send them.

Constants

HEADER_RIVET_RAY_ID

Bounded correlation string that follows work across actors, surviving sampling and trace-root boundaries.

HEADER_TRACEPARENT

HEADER_TRACESTATE

RAY_BAGGAGE_KEY

W3C Baggage key that carries a ray ID through application code, so a request handler that received a ray ID can hand it to the actors it calls.

Functions

bounded_ray_id

Returns value when it is a ray ID the runtime accepts: 1 to 30 characters of [A-Za-z0-9_-]. The value arrives from a caller, so anything else counts as absent.
