Enum EventSubscriptionError 

#[non_exhaustive]
pub enum EventSubscriptionError {
    NotAttached,
    ShuttingDown,
    CapacityExceeded,
    DuplicateIdentity,
    Start(StartError),
}

Failure before an outbound subscription owns runtime work.

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.

NotAttached

The client has not been attached to a dispatcher yet.

ShuttingDown

Dispatcher shutdown has atomically closed admission.

CapacityExceeded

A peer-driven or configured client bound was reached.

DuplicateIdentity

The caller reused an active Call-ID.

Start(StartError)

The pure client rejected the start fields.
