Enum bow::Bow

pub enum Bow<'a, T: 'a + ToBox + ?Sized> {
    Borrowed(&'a T),
    Boxed(Box<T>),
}

Like a Cow, using ToBox instead of ToBoxed.

Variants

Borrowed(&'a T)

Borrowed data.

Boxed(Box<T>)

Boxed data.

Methods

impl<'a, T: 'a + ToBox + ?Sized> Bow<'a, T>

fn to_mut(&mut self) -> &mut T

Acquires a mutable reference to the data.

Boxes the data if it is not already boxed.

fn into_box(self) -> Box<T>

Extracts the data as a box.
