Enum WithServicesError 

pub enum WithServicesError {
    SharedRingRoutingDeferred {
        service: &'static str,
    },
    SharedRingKindMismatch {
        slot: &'static str,
        handle: &'static str,
    },
}

Typed construction error for Scheduler::with_services.

Distinct from the String returned for genuine spawn/OS failures: a composition request that names a capability this release cannot deliver SAFELY is refused loudly and by name, rather than silently degraded.

Variants

SharedRingRoutingDeferred

A shared file/generic IO ring was injected, but cross-scheduler completion routing does not ship until the §3.9 routing gate lands with its mechanism in commit 6 (spec §3.9). service is the inventory label of the refused ring. Injecting it now would let the ring owner swallow the second scheduler’s completions.

Fields

service: &'static str

Inventory label of the refused ring (e.g. "file-io-ring").

SharedRingKindMismatch

A SharedIoRing handle built for one ring service was passed to a DIFFERENT service’s builder slot (e.g. SharedIoRing::generic(..) to SchedulerServices::shared_file_io). Reported distinctly so the diagnostic names the actual mistake instead of misattributing the deferred-routing refusal to the wrong service.

Fields

slot: &'static str

The builder slot the handle was passed to.

handle: &'static str

The service the handle itself was built for.
