Struct rt_ref::Ref

pub struct Ref<'a, V>
where
    V: 'a,
{ /* private fields */ }

Reference to a value.

Implementations

impl<'a, V> Ref<'a, V>

pub fn new(inner: CellRef<'a, V>) -> Self

Returns a new Ref.

pub fn try_clone(&self) -> Result<Self, RefOverflow>

Returns a clone of this Ref.

This method allows handling of reference overflows, but:

• Having 2 billion (32-bit system) / 9 quintillion (64-bit system) references to an object is not a realistic scenario in most applications.

• Applications that hold Refs with an ever-increasing reference count are not supported by this library.

  Reaching isize::MAX may be possible with std::mem::forget(Ref::clone(&r)).

Trait Implementations

impl<'a, V> Clone for Ref<'a, V>

fn clone(&self) -> Self

Returns a clone of this Ref.

Panics

Panics if the number of references is isize::MAX:

• Having 2 billion / 9 quintillion references to an object is not a realistic scenario in most applications.

• Applications that hold Refs with an ever-increasing reference count are not supported by this library.

  Reaching isize::MAX may be possible with std::mem::forget(Ref::clone(&r)).

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

Performs copy-assignment from source.

impl<'a, V> Debug for Ref<'a, V>

where V: Debug + 'a,

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

Formats the value using the given formatter.

impl<'a, V> Deref for Ref<'a, V>

type Target = V

The resulting type after dereferencing.

fn deref(&self) -> &V

Dereferences the value.

impl<'a, V> PartialEq for Ref<'a, V>

where V: PartialEq + 'a,

fn eq(&self, other: &Self) -> 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.
