Struct CVBuffer 

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

Available on crate feature cv only.

Generic CVBufferRef wrapper.

Implementations

impl CVBuffer

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

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

Safety

A non-null ptr must be a live CVBufferRef 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 CVBufferRef and returns an owned wrapper.

Safety

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

pub fn from_pixel_buffer(pixel_buffer: &CVPixelBuffer) -> Option<Self>

Wrap a pixel buffer as a generic CVBuffer.

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

Borrow the raw +0 CVBufferRef while self remains alive.

pub fn set_attachment( &self, key: &CFString, value: &dyn AsCFType, mode: CVAttachmentMode, )

Attach a Core Foundation value to the buffer.

pub fn attachment(&self, key: &CFString) -> Option<CFType>

Copy an attachment value for key.

pub fn attachments(&self, mode: CVAttachmentMode) -> Option<CFDictionary>

Copy all attachments for the requested propagation mode.

pub fn remove_all_attachments(&self)

Remove all attachments.

Trait Implementations

impl Clone for CVBuffer

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 CVBuffer

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

Formats the value using the given formatter.

impl Drop for CVBuffer

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.

impl Eq for CVBuffer

impl Hash for CVBuffer

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CVBuffer

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
