pub const WRITER_ADMISSION_SCOPE: &str = "writer_admission";Expand description
Stable ADR-131:251 scope discriminator carried on a
WRITER_QUEUE_SATURATED_STAGE failure — distinguishes write-queue
admission saturation from other unavailable failure kinds that share
the same retryable: true shape but are not bounded by the admission
deadline (e.g. WRITER_POOL_CHECKOUT_TIMEOUT_STAGE, which has no
ADR-131-defined scope and carries None).
