pub enum Transform<T, B = T> {
    Owned(T),
    Borrowed(B),
}

Methods

impl<T, B> Transform<T, B>

pub fn owned(self) -> T

Returns the Owned value if self is Owned.

Panics

Panics if self is Borrowed.

Example

use rocket::data::Transform;

let owned: Transform<usize, &[usize]> = Transform::Owned(10);
assert_eq!(owned.owned(), 10);

pub fn borrowed(self) -> B

Returns the Borrowed value if self is Borrowed.

Panics

Panics if self is Owned.

use rocket::data::Transform;

let borrowed: Transform<usize, &[usize]> = Transform::Borrowed(&[10]);
assert_eq!(borrowed.borrowed(), &[10]);
