Enum Refs 

pub enum Refs<'a, T> {
    Ref(&'a T),
    Arc(Arc<T>),
    Rc(Rc<T>),
    Box(Box<T>),
}

Enum used to represent a concrete varying pointer type which only needs to be accessed by ref. We avoid adding a Val(T) variant in order to keep the size of the enum minimal

Variants

Ref(&'a T)

Arc(Arc<T>)

Rc(Rc<T>)

Box(Box<T>)

Trait Implementations

impl<T> AsRef<T> for Refs<'_, T>

fn as_ref(&self) -> &T

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

impl<T> Deref for Refs<'_, T>

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

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

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

Converts to this type from the input type.

impl<T> From<Arc<T>> for Refs<'_, T>

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

Converts to this type from the input type.

impl<T> From<Box<T>> for Refs<'_, T>

fn from(b: Box<T>) -> Self

Converts to this type from the input type.

impl<T> From<Rc<T>> for Refs<'_, T>

fn from(r: Rc<T>) -> Self

Converts to this type from the input type.
