pub struct LensRegistry { /* private fields */ }

A registry of lenses with a single shared dispatcher.

Implementations

impl LensRegistry

pub fn new() -> Self

An empty registry.

pub fn register(&mut self, lens: Lens)

Register a lens (last registration of an id wins on exact ties).

pub fn get(&self, id: &Symbol) -> Option<&Lens>

Look up a lens by id.

pub fn lenses(&self) -> &[Lens]

All registered lenses.

pub fn dispatch_view( &self, cx: &mut Cx, target: &Expr, ctx: &DispatchContext<'_>, ) -> Result<DispatchOutcome>

Dispatch a View lens for target.

pub fn dispatch_editor( &self, cx: &mut Cx, target: &Expr, ctx: &DispatchContext<'_>, ) -> Result<DispatchOutcome>

Dispatch an Editor lens for target.

pub fn dispatch( &self, cx: &mut Cx, kind: LensKind, target: &Expr, ctx: &DispatchContext<'_>, ) -> Result<DispatchOutcome>

Resolve a lens of kind for target per the documented order.

impl LensRegistry

pub fn render_embedded( &self, cx: &mut Cx, lens_id: &Symbol, value: &Expr, ) -> Result<Expr>

Render value through the named view lens and return it wrapped in a scene/embed node, ready to nest inside a host lens’s Scene.

impl LensRegistry

pub fn render( &self, cx: &mut Cx, lens_id: &Symbol, value: &Expr, ) -> Result<Expr>

Render value through the named view lens, validating the emitted Scene.

pub fn propose( &self, cx: &mut Cx, lens_id: &Symbol, value: &Expr, intent: &Expr, ) -> Result<Draft>

Fold an Intent into a draft through the named editor lens, after the Intent passes structural validation.

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

Commit a committable draft through the named editor lens.

impl LensRegistry

pub fn lens_stack( &self, cx: &mut Cx, kind: LensKind, target: &Expr, ctx: &DispatchContext<'_>, ) -> Result<Vec<LensStackEntry>>

Build the ordered lens stack of kind for target: every eligible lens best first, with the universal default last. Capability-denied lenses are excluded.

Trait Implementations

impl Default for LensRegistry

fn default() -> LensRegistry

Returns the “default value” for a type.
