Enum Ref

pub enum Ref<'a, T> {
    Owned(T),
    Borrow(&'a T),
    Arc(Arc<T>),
}

Represents a reference to a value of type T.

Due to Rust’s temporal borrowing rules, returning a reference to a value may not be always possible, so this enum is used to represent one by having multiple variants for multiple types of references.

Variants

Owned(T)

An owned value. Useful for Copy types.

Borrow(&'a T)

A borrowed reference.

Arc(Arc<T>)

An Arc reference.

Trait Implementations

impl<'a, T> Deref for Ref<'a, T>

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

impl<'a, T> From<&'a T> for Ref<'a, T>

fn from(value: &'a T) -> Self

Converts to this type from the input type.

impl<'a, T> From<Arc<T>> for Ref<'a, T>

fn from(value: Arc<T>) -> Self

Converts to this type from the input type.

impl<'a, T> From<T> for Ref<'a, T>

fn from(value: T) -> Self

Converts to this type from the input type.
