Either crate Either documentation minimum rustc 1.63 build status

The enum Either with variants Left and Right is a general purpose sum type with two cases.

Either has methods that are similar to Option and Result, and it also implements traits like Iterator, Read, and Write.

The crate includes macros try_left!() and try_right!() to use for short-circuiting logic, similar to how the ? operator is used with Result. Note that Either is general purpose and unopinionated about the meaning of Left and Right. For describing success or error, use the regular Result.

Please read the API documentation here, and see RELEASES.md for the version history.
