Struct VTMultiPassStorage

#[repr(C)]
pub struct VTMultiPassStorage { /* private fields */ }

Available on crate feature VTMultiPassStorage only.

A mechanism for storing information for each frame of a multi-pass compression session.

VTMultiPassStorageRef is a CF type, so call CFRelease and CFRetain to manage objects of this type. The data stored in the VTMultiPassStorage is private to the video encoder.

Methods from Deref<Target = CFType>

pub fn downcast_ref<T>(&self) -> Option<&T>

where T: ConcreteType,

Available on crate feature VTSession only.

Attempt to downcast the type to that of type T.

This is the reference-variant. Use CFRetained::downcast if you want to convert a retained type. See also ConcreteType for more details on which types support being converted to.

fn borrow(&self) -> &AnyObject

Immutably borrows from an owned value.

impl Borrow<CFType> for VTMultiPassStorage

fn borrow(&self) -> &CFType

Immutably borrows from an owned value.

impl ConcreteType for VTMultiPassStorage

fn type_id() -> CFTypeID

Get the unique CFTypeID identifier for the type.

impl Debug for VTMultiPassStorage

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

Formats the value using the given formatter.

impl Deref for VTMultiPassStorage

type Target = CFType

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Hash for VTMultiPassStorage

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

Feeds this value into the given Hasher.

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

impl Message for VTMultiPassStorage

fn retain(&self) -> Retained<Self>

where Self: Sized,

Increment the reference count of the receiver.

impl PartialEq for VTMultiPassStorage

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Type for VTMultiPassStorage

fn retain(&self) -> CFRetained<Self>

where Self: Sized,
