Enum RegisterWaitError 

pub enum RegisterWaitError {
    UnknownSubscriptionSet(SubscriptionSetId),
    UnexpectedWheelRegion(Region),
}

register_wait’s one failure mode. See this module’s doc comment for why this exists instead of the plan’s literal -> ().

Variants

UnknownSubscriptionSet(SubscriptionSetId)

WaitSpec::ImplicitComb’s SubscriptionSetId had no entry in the caller-supplied lookup (codegen’s real static-sensitivity table does not exist yet in this wave — the plan’s own text names this as an in-crate test fixture stand-in).

UnexpectedWheelRegion(Region)

TimeWheel::arm_delay is documented to return only Region::Active or Region::Inactive. This variant exists purely so this function’s own dispatch on that return value stays an exhaustive match over the full 7-variant Region type with no wildcard arm (this workspace’s “loud typed error, never a silent no-op” posture), catching a future change to arm_delay’s contract at this call site instead of silently mishandling it. sva T1 (§1.4, review fix, blocking finding 2) folded Region::Preponed into this same defensive arm alongside Nba/Reactive/Postponed; sva T2 (review fix, blocking finding 2), Observed’s half, folds Region::Observed into it too, for the identical reason.

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
