Enum nb::Error

source ·
pub enum Error<E> {
    Other(E),
    WouldBlock,
}
Expand description

A non-blocking error

The main use of this enum is to add a WouldBlock variant to an existing error enum.

Variants§

§

Other(E)

A different kind of error

§

WouldBlock

This operation requires blocking behavior to complete

Implementations§

source§

impl<E> Error<E>

source

pub fn map<T, F>(self, op: F) -> Error<T>
where F: FnOnce(E) -> T,
