Struct CVMetalTextureCache 

pub struct CVMetalTextureCache(/* private fields */);

Available on crate feature cv only.

Owned wrapper around CVMetalTextureCacheRef.

Implementations

impl CVMetalTextureCache

pub fn system_default() -> Option<Self>

Create a texture cache using the system-default Metal device.

pub unsafe fn from_raw(ptr: *mut c_void) -> Option<Self>

Adopts a +1 retained CVMetalTextureCacheRef and returns None for null.

Safety

A non-null ptr must be a live CVMetalTextureCacheRef of the exact type carrying one retain transferred to this wrapper. The caller must not release or separately adopt that transferred retain.

pub unsafe fn from_raw_borrowed(ptr: *mut c_void) -> Option<Self>

Retains a +0 borrowed cache pointer and returns an owned wrapper.

Safety

A non-null ptr must be a live CVMetalTextureCacheRef of the exact type for the duration of the retain call.

pub const fn as_ptr(&self) -> *mut c_void

Borrow the raw +0 cache pointer while self remains alive.

pub fn type_id() -> usize

Core Video type identifier.

pub fn flush(&self)

Flush pending cached textures.

Trait Implementations

impl Clone for CVMetalTextureCache

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CVMetalTextureCache

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

Formats the value using the given formatter.

impl Drop for CVMetalTextureCache

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
