Enum rocket::data::Transform

source ·
pub enum Transform<T, B = T> {
    Owned(T),
    Borrowed(B),
}
Expand description

Indicates how incoming data should be transformed before being parsed and validated by a data guard.

See the documentation for FromData for usage details.

Variants§

§

Owned(T)

Indicates that data should be or has been transformed into the FromData::Owned variant.

§

Borrowed(B)

Indicates that data should be or has been transformed into the FromData::Borrowed variant.

Implementations§

source§

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

source

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);
source

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]);
