Enum CallbackError 

pub enum CallbackError<E> {
    Processing(Error),
    Callback(E),
}

A callback-backed query that could not finish.

The wrapper allocates no storage. Any owned callback error data must retain its own resource accounting until it is dropped.

Variants

Processing(Error)

Shared processing failed, including a located resource refusal.

Callback(E)

The caller’s callback failed, preserving its original cause.
