Enum mown::Mown

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

Container for borrowed or owned value.

Variants

Owned(T::Owned)

Owned value.

Borrowed(&'a T)

Borrowed value.

Implementations

impl<'a, T: ?Sized + Borrowed> 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.

pub fn into_owned(self) -> <T as Borrowed>::Owned

where T: ToOwned<Owned = <T as Borrowed>::Owned>,

Trait Implementations

impl<'a, T: ?Sized + Borrowed> AsRef<T> for Mown<'a, T>

fn as_ref(&self) -> &T

Converts this type into a shared reference of the (usually inferred) input type.

impl<'a, T: ?Sized + Borrowed + Debug> Debug for Mown<'a, T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, T: ?Sized + Borrowed> Deref for Mown<'a, T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<'a, T: ?Sized + Borrowed + Display> Display for Mown<'a, T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, T: ?Sized + Borrowed, Q: Borrow<T>> From<&'a Q> for Mown<'a, T>

fn from(r: &'a Q) -> Mown<'a, T>

Converts to this type from the input type.

impl<'a, T: ?Sized + Borrowed + Hash> Hash for Mown<'a, T>

fn hash<H: Hasher>(&self, hasher: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<'a, T: ?Sized + Borrowed + PartialEq> PartialEq for Mown<'a, T>

fn eq(&self, other: &Mown<'a, T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a, T: ?Sized + Borrowed + PartialOrd> PartialOrd for Mown<'a, T>

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

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
