Struct beef::Cow

pub struct Cow<'a, T: Beef + ?Sized + 'a> { /* fields omitted */ }

A clone-on-write smart pointer, mostly compatible with std::borrow::Cow.

Methods

impl<'_, B: ?Sized> Cow<'_, B> where
    B: Beef, 

pub fn owned(val: B::Owned) -> Self

Owned data.

impl<'a, T: ?Sized> Cow<'a, T> where
    T: Beef, 

pub fn borrowed(val: &'a T) -> Self

Owned data.

pub fn into_owned(self) -> T::Owned

Extracts the owned data.

Clones the data if it is not already owned.
