Enum mown::Mown

pub enum Mown<'a, T: ?Sized + ToOwned> {
    Owned(T::Owned),
    Borrowed(&'a T),
}

Container for borrowed or owned value.

Variants

Owned(T::Owned)

Owned value.

Borrowed(&'a T)

Borrowed value.

Methods

impl<'a, T: ?Sized + ToOwned> Mown<'a, T>

pub fn is_owned(&self) -> bool

Checks if the value is owned.

pub fn is_borrowed(&self) -> bool

Checks if the value is borrowed.

pub fn as_mut(&mut self) -> Option<&mut T> where
    T::Owned: BorrowMut<T>, 

Returns the owned value as a mutable reference, if any.

If the value is borrowed, returns None.

impl<'a, T: ?Sized + ToOwned + Ord> Ord for Mown<'a, T>

fn cmp(&self, other: &Mown<'a, T>) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.
