Enum OwnedOrMutRef

pub enum OwnedOrMutRef<'r, T> {
    Owned(T),
    MutRef(&'r mut T),
}

Holds an owned T or a mutable reference.

Variants

Owned(T)

Holds an owned T.

MutRef(&'r mut T)

Holds a mutable reference to T.

Implementations

impl<'r, T> OwnedOrMutRef<'r, T>

pub fn reborrow(&mut self) -> OwnedOrMutRef<'_, T>

Reborrows this OwnedOrMutRef with a shorter lifetime.

For an Owned variant, this borrows it as a MutRef.

Trait Implementations

impl<'r, T: Debug> Debug for OwnedOrMutRef<'r, T>

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

Formats the value using the given formatter.

impl<'r, T> Deref for OwnedOrMutRef<'r, T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'r, T> DerefMut for OwnedOrMutRef<'r, T>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<'r, T> From<&'r mut T> for OwnedOrMutRef<'r, T>

fn from(v: &'r mut T) -> Self

Converts to this type from the input type.

impl<'r, T> From<T> for OwnedOrMutRef<'r, T>

fn from(v: T) -> Self

Converts to this type from the input type.

impl<'r, T: PartialEq> PartialEq for OwnedOrMutRef<'r, T>

fn eq(&self, other: &OwnedOrMutRef<'r, T>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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