# Enum sp_runtime::Either[−][src]

``````pub enum Either<L, R> {
Left(L),
Right(R),
}``````
Expand description

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

The `Either` type is symmetric and treats its variants the same way, without preference. (For representing success or error, use the regular `Result` enum instead.)

## Variants

`Left(L)`

A value of type `L`.

### Tuple Fields of Left

`0: L`
`Right(R)`

A value of type `R`.

`0: R`

## Implementations

Return true if the value is the `Left` variant.

``````use either::*;

let values = [Left(1), Right("the right value")];
assert_eq!(values[0].is_left(), true);
assert_eq!(values[1].is_left(), false);``````

Return true if the value is the `Right` variant.

``````use either::*;

let values = [Left(1), Right("the right value")];
assert_eq!(values[0].is_right(), false);
assert_eq!(values[1].is_right(), true);``````

Convert the left side of `Either<L, R>` to an `Option<L>`.

``````use either::*;

let left: Either<_, ()> = Left("some value");
assert_eq!(left.left(),  Some("some value"));

let right: Either<(), _> = Right(321);
assert_eq!(right.left(), None);``````

Convert the right side of `Either<L, R>` to an `Option<R>`.

``````use either::*;

let left: Either<_, ()> = Left("some value");
assert_eq!(left.right(),  None);

let right: Either<(), _> = Right(321);
assert_eq!(right.right(), Some(321));``````

Convert `&Either<L, R>` to `Either<&L, &R>`.

``````use either::*;

let left: Either<_, ()> = Left("some value");
assert_eq!(left.as_ref(), Left(&"some value"));

let right: Either<(), _> = Right("some value");
assert_eq!(right.as_ref(), Right(&"some value"));``````

Convert `&mut Either<L, R>` to `Either<&mut L, &mut R>`.

``````use either::*;

fn mutate_left(value: &mut Either<u32, u32>) {
if let Some(l) = value.as_mut().left() {
*l = 999;
}
}

let mut left = Left(123);
let mut right = Right(123);
mutate_left(&mut left);
mutate_left(&mut right);
assert_eq!(left, Left(999));
assert_eq!(right, Right(123));``````

Convert `Either<L, R>` to `Either<R, L>`.

``````use either::*;

let left: Either<_, ()> = Left(123);
assert_eq!(left.flip(), Right(123));

let right: Either<(), _> = Right("some value");
assert_eq!(right.flip(), Left("some value"));``````

Apply the function `f` on the value in the `Left` variant if it is present rewrapping the result in `Left`.

``````use either::*;

let left: Either<_, u32> = Left(123);
assert_eq!(left.map_left(|x| x * 2), Left(246));

let right: Either<u32, _> = Right(123);
assert_eq!(right.map_left(|x| x * 2), Right(123));``````

Apply the function `f` on the value in the `Right` variant if it is present rewrapping the result in `Right`.

``````use either::*;

let left: Either<_, u32> = Left(123);
assert_eq!(left.map_right(|x| x * 2), Left(123));

let right: Either<u32, _> = Right(123);
assert_eq!(right.map_right(|x| x * 2), Right(246));``````

Apply one of two functions depending on contents, unifying their result. If the value is `Left(L)` then the first function `f` is applied; if it is `Right(R)` then the second function `g` is applied.

``````use either::*;

fn square(n: u32) -> i32 { (n * n) as i32 }
fn negate(n: i32) -> i32 { -n }

let left: Either<u32, i32> = Left(4);
assert_eq!(left.either(square, negate), 16);

let right: Either<u32, i32> = Right(-4);
assert_eq!(right.either(square, negate), 4);``````

Like `either`, but provide some context to whichever of the functions ends up being called.

``````// In this example, the context is a mutable reference
use either::*;

let mut result = Vec::new();

let values = vec![Left(2), Right(2.7)];

for value in values {
value.either_with(&mut result,
|ctx, integer| ctx.push(integer),
|ctx, real| ctx.push(f64::round(real) as i32));
}

assert_eq!(result, vec![2, 3]);``````

Apply the function `f` on the value in the `Left` variant if it is present.

``````use either::*;

let left: Either<_, u32> = Left(123);
assert_eq!(left.left_and_then::<_,()>(|x| Right(x * 2)), Right(246));

let right: Either<u32, _> = Right(123);
assert_eq!(right.left_and_then(|x| Right::<(), _>(x * 2)), Right(123));``````

Apply the function `f` on the value in the `Right` variant if it is present.

``````use either::*;

let left: Either<_, u32> = Left(123);
assert_eq!(left.right_and_then(|x| Right(x * 2)), Left(123));

let right: Either<u32, _> = Right(123);
assert_eq!(right.right_and_then(|x| Right(x * 2)), Right(246));``````

Convert the inner value to an iterator.

``````use either::*;

let left: Either<_, Vec<u32>> = Left(vec![1, 2, 3, 4, 5]);
let mut right: Either<Vec<u32>, _> = Right(vec![]);
right.extend(left.into_iter());
assert_eq!(right, Right(vec![1, 2, 3, 4, 5]));``````

Return left value or given value

Arguments passed to `left_or` are eagerly evaluated; if you are passing the result of a function call, it is recommended to use `left_or_else`, which is lazily evaluated.

# Examples

``````let left: Either<&str, &str> = Left("left");
assert_eq!(left.left_or("foo"), "left");

let right: Either<&str, &str> = Right("right");
assert_eq!(right.left_or("left"), "left");``````

Return left or a default

# Examples

``````let left: Either<String, u32> = Left("left".to_string());
assert_eq!(left.left_or_default(), "left");

let right: Either<String, u32> = Right(42);
assert_eq!(right.left_or_default(), String::default());``````

Returns left value or computes it from a closure

# Examples

``````let left: Either<String, u32> = Left("3".to_string());
assert_eq!(left.left_or_else(|_| unreachable!()), "3");

let right: Either<String, u32> = Right(3);
assert_eq!(right.left_or_else(|x| x.to_string()), "3");``````

assert_eq!(right.right_or("foo"), "right");

let left: Either<&str, &str> = Left("left");

Return right or a default

# Examples

let right: Either<String, u32> = Right(42);
assert_eq!(right.right_or_default(), 42);``````
