impl OutputQueue

pub fn new(num_buffers: usize) -> Self

Creates a new output queue capable of containing num_buffers buffers.

pub fn import_buffer( &mut self, picture_buffer_id: u32, resource: GuestResource, ) -> Result<(), OutputBufferImportError>

Import a buffer, i.e. associate the buffer’s resource to a given picture_buffer_id, and make the buffer ready for use.

A buffer with a given picture_buffer_id can only be imported once.

pub fn reuse_buffer( &mut self, picture_buffer_id: u32, ) -> Result<(), OutputBufferReuseError>

Mark the previously-imported buffer with ID picture_buffer_id as ready for being used.

pub fn try_get_ready_buffer(&mut self) -> Option<(u32, &mut GuestResource)>

Get a buffer ready to be decoded into, if any is available.

pub fn clear_ready_buffers(&mut self)

Auto Trait Implementations§

impl UnwindSafe for OutputQueue

Blanket Implementations§

impl<T> Any for T
where T: 'static + ?Sized,

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<T> Borrow<T> for T
where T: ?Sized,

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> BorrowMut<T> for T
where T: ?Sized,

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

impl<T> Downcast for T
where T: Any,

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

impl<T> DowncastSync for T
where T: Any + Send + Sync,

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Send + Sync>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
