Enum nb::Error

[−] Show declaration

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)

[−] Expand description

A different kind of error

WouldBlock

[−] Expand description

This operation requires blocking behavior to complete

Implementations

impl<E> Error<E>[−]

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

Maps an Error<E> to Error<T> by applying a function to a contained Error::Other value, leaving an Error::WouldBlock value untouched.
