Expand description
Keyed fleet counters backed by one authoritative SHM table.
A counter is current state, not history: no ring frame is published and
no cursor exists. The owner of a fleet generation calls Counter::reset_all
during quiescent boot; everything else is lock-free atomics on
immutable-address slots.
Keys are installed once per fleet generation under a short, process-recoverable structural lock. Once installed, their values are immutable-address, signed 64-bit atomics: reads and updates do not publish ring frames and do not acquire an OS lock.
Structs§
- Counter
- Fleet-wide keyed signed counters.
Enums§
- Error
- Additions are expected: a cause discovered later lands here rather than in a new major version, so a caller matches what it handles and leaves the rest to a catch-all.
Constants§
- COUNTER_
CAPACITY - Maximum number of distinct keys installed during one fleet generation.
- COUNTER_
KEY_ MAX - Maximum counter key length in bytes.
- COUNTER_
STATE_ KIND - Reserved Orbit SHM kind for the keyed counter table.
