Enum SessionFailure 

#[non_exhaustive]
pub enum SessionFailure {
    SubmissionCapacityTooSmall,
    CompletionCapacityTooSmall,
    WorkObject,
}

Why a session could not be built.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SubmissionCapacityTooSmall

The submission ring could not carry one enumeration.

It needs room for the session’s standing abandon message, one enumeration’s reserved cancellation, and one ordinary begin.

CompletionCapacityTooSmall

The completion ring could not carry one enumeration.

It needs room for one reserved terminal outcome and one entry, and reservations never take the last slot.

WorkObject

Windows refused to create the servicer’s thread-pool work object.
