Module context 

Trace context ingestion and the exchange join buffer (spec 028, 3.7): bounded tables, entries removed on delivery, on abandon or after their time to live by the sink’s monotonic clock.

Structs

Context

One registered decision (3.7.1).

ContextTable

The bounded table of registered decisions.

JoinBuffer

Exchange records waiting for their decision (3.7.3), keyed by attempt id, and a bounded memory of attempts already exported so a late record is counted at once.

TraceParent

A parsed W3C traceparent (version 00 layout; a later version is read by its first four fields, as the W3C specification requires).

Enums

Joined

What JoinBuffer::insert did with a record.

Constants

EXPORTED_MEMORY

Attempt ids remembered as exported, at least (the buffer’s own bound when larger): a record for one of them is exchange_unjoined at once.

Functions

parse_traceparent

Parse a traceparent. None when it does not parse, has version ff, or has an all-zero trace or parent id (3.7.1).
