# [−][src]Crate either

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

Crate features:

- `"use_std"` Enabled by default. Disable to make the library `#![no_std]`.

- `"serde"` Disabled by default. Enable to `#[derive(Serialize, Deserialize)]` for `Either`

## Re-exports

`pub use Either::Left;`
`pub use Either::Right;`

## Macros

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.

## Enums

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
