Struct leptonica_plumbing::memory::RefCounted

source · 
pub struct RefCounted<T: LeptonicaDestroy> { /* private fields */ }
Expand description

A wrapper for ref counted leptonica pointers.

Implementations§

source§

impl<T: LeptonicaDestroy> RefCounted<T>

source

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

Creates a new ref counted 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.
