Struct skia_safe::RefHandle

#[repr(transparent)]
pub struct RefHandle<N: NativeDrop>(_);

A wrapper type that represents a native type with a pointer to the native object.

Trait Implementations

impl<N: NativeDrop> Drop for RefHandle<N>

fn drop(&mut self)

Executes the destructor for this type.

impl<N: NativeDrop + NativePartialEq> PartialEq<RefHandle<N>> for RefHandle<N>

fn eq(&self, rhs: &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.

impl<N> PointerWrapper<N> for RefHandle<N>where N: NativeDrop,

fn wrap(ptr: *mut N) -> Option<Self>

Wraps a native pointer into a wrapper type. Returns None if the pointer is null.

fn unwrap(self) -> *mut N

Unwraps the wrapper type into the native pointer.

fn inner(&self) -> &N

Access the wrapped pointer.

fn inner_mut(&mut self) -> &mut N

Access the wrapped pointer.
