Modules

into_either 🔒

The trait IntoEither provides methods for converting a type Self, whose size is constant and known at compile-time, into an Either variant.

iterator 🔒

Macros

check_t 🔒

A helper macro to check if AsRef and AsMut are implemented for a given type.

for_both

Evaluate the provided expression for both Either::Left and Either::Right.

impl_specific_ref_and_mut 🔒

map_either 🔒

try_left

Macro for unwrapping the left side of an Either, which fails early with the opposite side. Can only be used in functions that return Either because of the early return of Right that it provides.

try_right

Dual to try_left!, see its documentation for more information.

Structs

IterEither

Iterator that maps left or right iterators to corresponding Either-wrapped items.
