Expand description

One reversible surface codec: encode a value to a projected Scene, decode an Intent to a Draft, and commit a Draft to a checked Operation.

Implementors back both directions with one definition. PairCodec adapts a legacy (View, Editor) pair to this contract.

Required Methods§

Source

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

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

Source

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

Decodes intent against value into a previewable Draft.

Source

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

Commits a committable Draft into a checked Operation.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
