Trait Implementations

impl<N> AsRef<RCHandle<N>> for RCHandle<N>where N: NativeRefCounted,

fn as_ref(&self) -> &RCHandle<N>

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

impl<N> Clone for RCHandle<N>where N: NativeRefCounted,

fn clone(&self) -> RCHandle<N>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<H> ConditionallySend for RCHandle<H>where H: NativeRefCountedBase,

RCHandle<H> is conditionally Send and can be sent to another thread when its reference count is 1.

fn can_send(&self) -> bool

Returns true if the handle can be sent to another thread.

fn wrap_send(self) -> Result<Sendable<RCHandle<H>>, RCHandle<H>>

Wrap the handle in a type that can be sent to another thread and unwrapped there.

impl Debug for RCHandle<SkShader>

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

Formats the value using the given formatter.

impl Default for RCHandle<SkShader>

fn default() -> RCHandle<SkShader>

Returns the “default value” for a type.

impl<N> Drop for RCHandle<N>where N: NativeRefCounted,

fn drop(&mut self)

Executes the destructor for this type.

impl<N> Flattenable for RCHandle<N>where N: NativeFlattenable + NativeRefCountedBase,

fn type_name(&self) -> &CStr

fn serialize(&self) -> RCHandle<SkData>

fn deserialize(data: &[u8]) -> Option<RCHandle<N>>

impl<N> From<&RCHandle<N>> for RCHandle<N>where N: NativeRefCounted,

A reference counted handle is cheap to clone, so we do support a conversion from a reference to a ref counter to an owned handle.

fn from(rch: &RCHandle<N>) -> RCHandle<N>

Converts to this type from the input type.

impl<N> PartialEq<RCHandle<N>> for RCHandle<N>where N: NativeRefCounted + NativePartialEq,

fn eq(&self, rhs: &RCHandle<N>) -> 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 RCHandle<N>where N: NativeRefCounted,

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

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.
