Struct MetalOwnedTextureFrameHandle 

pub struct MetalOwnedTextureFrameHandle { /* private fields */ }

RAII guard for an acquired Metal session-owned texture frame.

Releasing the guard ends the borrow of the backend Metal texture and device.

Implementations

impl MetalOwnedTextureFrameHandle

pub fn frame(&self) -> Result<&MetalOwnedTextureFrame>

Returns copied metadata for this acquired frame.

pub fn is_closed(&self) -> bool

pub unsafe fn texture(&self) -> Result<FrameNativePointer<'_>>

Returns the borrowed Metal texture pointer for backend interop.

Safety

The returned pointer is valid only while this frame handle remains open. The caller must not store or use it after frame release and must satisfy Metal synchronization and thread-affinity requirements.

pub unsafe fn device(&self) -> Result<FrameNativePointer<'_>>

Returns the borrowed Metal device pointer for backend interop.

Safety

The returned pointer has the same lifetime and synchronization requirements as MetalOwnedTextureFrameHandle::texture.

pub fn close(self) -> Result<(), HandleOperationError<Self>>

Explicitly releases this frame.

Trait Implementations

impl Debug for MetalOwnedTextureFrameHandle

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

Formats the value using the given formatter.

impl Drop for MetalOwnedTextureFrameHandle

fn drop(&mut self)

Executes the destructor for this type.
