Struct PairCodec 

pub struct PairCodec { /* private fields */ }

Adapts a (View, Editor) pair to the unified SurfaceCodec.

encode runs the view forward then projects to the surface via reduce_for_caps; decode/commit delegate to the editor.

Implementations

impl PairCodec

pub fn new(view: Arc<dyn View>, editor: Arc<dyn Editor>) -> Self

Pairs a view and an editor into one reversible codec.

Trait Implementations

impl SurfaceCodec for PairCodec

fn encode(&self, cx: &mut Cx, value: &Expr, caps: &SurfaceCaps) -> Result<Expr>

Renders value to a Scene projected for caps (deterministic).

fn decode(&self, cx: &mut Cx, value: &Expr, intent: &Expr) -> Result<Draft>

Decodes intent against value into a previewable Draft.

fn commit(&self, cx: &mut Cx, draft: &Draft) -> Result<Operation>

Commits a committable Draft into a checked Operation.
