void-1.0.2
Void
The uninhabited void type for use in statically impossible cases.
Overview
The uninhabited type, enum Void { }
is useful in dealing with cases you
know to be impossible. For instance, if you are implementing a trait which
allows for error checking, but your case always succeeds, you can mark the
error case or type as Void
, signaling to the compiler it can never happen.
This crate also comes packed with a few traits offering extension methods to
Result<T, Void>
and Result<Void, T>
.
