Re-exports§

  • pub use crate::Either::Left;
  • pub use crate::Either::Right;

Macros§

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