Compile-time routing contract for a scheduler work class.

Implementors are zero-sized marker types. The scheduler monomorphizes dispatch per marker and uses the associated constants for deterministic worker selection without storing a runtime policy object.

Required Associated Constants

const AFFINITY_OFFSET: usize

Offset mixed into round-robin worker selection for this work class.

const SERIAL_AFFINITY_OFFSET: usize

Worker offset used for serial handoff when no queued backlog exists.

Serial result-bearing submit/join loops benefit from a single stable worker cache footprint. The value is an associated constant so the scheduler monomorphizes the routing decision per work class.

const NAME: &'static str

Stable diagnostic name for this work class.

const USES_ASYNC_LANE: bool

Whether this work class is eligible for asynchronous lane routing.

const USES_BLOCKING_LANE: bool

Whether this work class uses the dedicated bounded blocking lane.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
