Enum BackgroundMode 

pub enum BackgroundMode {
    Begin,
    End,
}

Whether the thread runs in background processing mode.

Background mode is not an I/O-priority knob on its own: entering it lowers CPU, I/O and memory priority together, and leaving it restores all three. The name says so rather than presenting it as an I/O setting that happens to have side effects.

Variants

Begin

Enter background processing mode for the operation.

End

Leave background processing mode for the operation.
