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.
A different kind of error
This operation requires blocking behavior to complete
Maps an Error<E>
to Error<T>
by applying a function to a contained
Error::Other
value, leaving an Error::WouldBlock
value untouched.

and other
values to be equal, and is used

This method tests for !=
. The default implementation is almost always
sufficient, and should not be overridden without very good reason.
