Implementations on Foreign Types

impl<T: Empty> Gettable for Option<T>

fn get(self) -> T

Moves the value v out of the Roption<T> if it is Some(v).

Panics

Panics if the self value equals None.

Safety note

In general, because this function may panic, its use is discouraged. Instead, prefer to use pattern matching and handle the None case explicitly.

Examples

let x = Some("air");
assert_eq!(x.get(), "air");

let x: Roption<&str> = None;
assert_eq!(x.get(), "air"); // fails

type Res = T

impl<T: Empty, E> Gettable for Result<T, E>

fn get(self) -> T

Safely unwraps a Result, yielding the content of an Ok.

Examples

let x: Rresult<u32, &str> = Ok(2);
assert_eq!(x.unwrap(), 2);

let x: Rresult<u32, &str> = Err("emergency failure");
x.get();

type Res = T
