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]);
