Trait DecodedHandle

pub trait DecodedHandle {
    type Descriptor;

    // Required methods
    fn dyn_picture<'a>(&'a self) -> Box<dyn DynHandle + 'a>;
    fn timestamp(&self) -> u64;
    fn coded_resolution(&self) -> Resolution;
    fn display_resolution(&self) -> Resolution;
    fn is_ready(&self) -> bool;
    fn sync(&self) -> Result<()>;
    fn resource(&self) -> Ref<'_, Self::Descriptor>;
}

The handle type used by the decoder backend. The only requirement from implementors is that they give access to the underlying handle and that they can be (cheaply) cloned.

Required Associated Types

type Descriptor

Memory descriptor type - the type that provides the backend memory for the decoded frame. () is a special type meaning that the backend is responsible for allocating and managing the memory itself.

Required Methods

fn dyn_picture<'a>(&'a self) -> Box<dyn DynHandle + 'a>

Returns a reference to an object allowing a CPU mapping of the decoded frame.

fn timestamp(&self) -> u64

Returns the timestamp of the picture.

fn coded_resolution(&self) -> Resolution

Returns the coded resolution at the time this handle was decoded.

fn display_resolution(&self) -> Resolution

Returns the display resolution at the time this handle was decoded.

fn is_ready(&self) -> bool

Returns true if this handle has been completely decoded.

fn sync(&self) -> Result<()>

Wait until this handle has been completely rendered.

fn resource(&self) -> Ref<'_, Self::Descriptor>

Returns a reference to the internal DecodedHandle::Descriptor. Can be leveraged by platform-specific code,
