Enum OwnedOrRef

pub enum OwnedOrRef<'r, T> {
    Owned(T),
    Ref(&'r T),
}

Holds an owned T or an immutable reference.

Variants

Owned(T)

Holds an owned T.

Ref(&'r T)

Holds an immutable reference to T.

Implementations

impl<'r, T> OwnedOrRef<'r, T>

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

Reborrows this OwnedOrRef with a shorter lifetime.

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

Trait Implementations

impl<'r, T: Clone> Clone for OwnedOrRef<'r, T>

fn clone(&self) -> OwnedOrRef<'r, T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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

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

Formats the value using the given formatter.

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

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

impl<'r, T> From<&'r T> for OwnedOrRef<'r, T>

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

Converts to this type from the input type.

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

fn from(v: T) -> Self

Converts to this type from the input type.

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

fn eq(&self, other: &OwnedOrRef<'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.
