Enum PollError 

pub enum PollError {
    UnknownRequest,
    WrongQueue,
    DriverPoisoned,
}

Queue misuse/query failure.

This is intentionally separate from request I/O completion. Returning this error must not tell the runtime that the DMA backing is safe to recycle.

Variants

UnknownRequest

WrongQueue

DriverPoisoned
