Detailed Description

Caller-owned one-job portable service state.

Correlates Start, Next, and Cancel independently of the concrete C6 HTTPS backend and retains no request/response pointers.

Invariant

An active service has non-zero active_job_id.

next_sequence and next_offset advance only after a successful read.

Since

0.1.0
