Struct SharedRef 

pub struct SharedRef<T>(/* private fields */)
where
    T: Shared;

Wrapper around a C++ shared_ptr. The shared_ptr is assumed to contain a value and may not be null.

Implementations

impl<T> SharedRef<T>

where T: Shared,

pub fn assert_use_count_eq(&self, expected: usize)

Asserts that the number of references to the shared inner value is equal to the expected count.

This function relies on the C++ method std::shared_ptr::use_count(), which usually performs a relaxed load. This function will repeatedly call use_count() until it returns the expected value, for up to one second. Therefore it should probably not be used in performance critical code.

Trait Implementations

impl<T> AsRef<T> for SharedRef<T>

where T: Shared,

fn as_ref(&self) -> &T

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

impl<T> Borrow<T> for SharedRef<T>

where T: Shared,

fn borrow(&self) -> &T

Immutably borrows from an owned value.

impl<T> Clone for SharedRef<T>

where T: Shared,

fn clone(&self) -> SharedRef<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for SharedRef<T>

where T: Debug + Shared,

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

Formats the value using the given formatter.

impl<T> Deref for SharedRef<T>

where T: Shared,

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &<SharedRef<T> as Deref>::Target

Dereferences the value.

impl<T> From<SharedRef<T>> for SharedPtr<T>

where T: Shared,

fn from(shared_ref: SharedRef<T>) -> SharedPtr<T>

Converts to this type from the input type.

impl<T> From<UniqueRef<T>> for SharedRef<T>

where T: Shared,

fn from(unique_ref: UniqueRef<T>) -> SharedRef<T>

Converts to this type from the input type.
