Struct Claim

Source

pub struct Claim {
    pub class: OpClass,
    pub bytes: u64,
    pub enqueued: Instant,
}

Expand description

What an admitted operation holds: a concurrency slot and a memory reservation, plus the instant it was admitted.

Deliberately not a Drop guard. The one guard is AdmissionGuard, which owns this; two Drops over one reservation is how a ledger comes to be released twice.

Fields§

§class: OpClass

The class, needed to release the right reservation and to file the sojourn under the right window.

§bytes: u64

What was reserved at admission (OpClass::admission_bytes). Everything charged afterwards is counted by the guard that owns this claim, so the release is bytes + grown and cannot drift.

§enqueued: Instant

Enqueue time — when the operation first asked for a slot, before any wait. The sojourn is measured from here.
