Struct Split 

pub struct Split<A> { /* private fields */ }

Runs one content encode and then many local adaptations.

The helper keeps device state out of the content encoder API. State is only accepted by Split::adapt_many and the free drive function, both of which operate on an already encoded EncodedScene.

Implementations

impl<A> Split<A>

pub fn new(adapter: A, profile: DeviceProfile) -> Self

Builds a split driver for one local adapter and device profile.

pub fn adapter(&self) -> &A

Returns the local adapter.

pub fn profile(&self) -> &DeviceProfile

Returns the device profile used for local adaptations.

impl<A: LocalAdapter> Split<A>

pub fn encode_once<C: SurfaceCodec + ?Sized>( &self, codec: &C, cx: &mut Cx, value: &Expr, caps: &SurfaceCaps, ) -> Result<EncodedScene>

Encodes content once through a SurfaceCodec.

pub fn adapt_one( &self, encoded: &EncodedScene, state: &A::State, ) -> Result<Rc<Expr>>

Adapts one already encoded Scene using the latest device state.

pub fn adapt_many( &self, encoded: &EncodedScene, states: &[A::State], ) -> Result<Vec<Rc<Expr>>>

Adapts one already encoded Scene for each device state.

pub fn run<C: SurfaceCodec + ?Sized>( &self, codec: &C, cx: &mut Cx, value: &Expr, caps: &SurfaceCaps, states: &[A::State], ) -> Result<SplitRun>

Runs the full split: one encode followed by local adaptations.

Trait Implementations

impl<A: Clone> Clone for Split<A>
