Struct leptonica_plumbing::memory::RefCountedExclusive

pub struct RefCountedExclusive<T: LeptonicaDestroy> { /* private fields */ }

A wrapper for ref counted leptonica pointers that can be safely mutated.

For example if it is the only reference.

Implementations

impl<T: LeptonicaDestroy> RefCountedExclusive<T>

pub unsafe fn new(inner: T) -> Self

Creates a new ref counted exclusive wrapper

Safety

It must be safe for this wrapper to destroy (decrement the ref count). The ref count must have already been incremented before being passed to new. The pointer must not be mutated whilst this wrapper exists, except via this wrapper.

impl<T: LeptonicaDestroy + LeptonicaClone> RefCountedExclusive<T>

pub fn to_ref_counted(self) -> RefCounted<T>

Convert to a ref counted wrapper

Trait Implementations

impl<T: LeptonicaDestroy> Deref for RefCountedExclusive<T>

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

impl<T: LeptonicaDestroy> DerefMut for RefCountedExclusive<T>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<T: LeptonicaDestroy> Drop for RefCountedExclusive<T>

fn drop(&mut self)

Executes the destructor for this type.
