Enum ProviderContextPinError 

pub enum ProviderContextPinError {
    ContextUnavailable(ProviderContextIdentity),
    PinCountOverflow(ProviderContextIdentity),
}

Why a provider/context pin could not be acquired.

Variants

ContextUnavailable(ProviderContextIdentity)

The context is retiring, lost, or terminated, so no new work may be attached to it. The caller must not queue the release.

PinCountOverflow(ProviderContextIdentity)

The implementation’s outstanding-work counter cannot represent another pin. Treated as a refusal rather than a wrap.
