Struct DefaultBinder 

pub struct DefaultBinder { /* private fields */ }

Stateless default binder. Holds a slot → Vec<BakedBody> map; on fire(event) walks the matching slot’s bodies in declaration order. Push 5 introduces a stateful TuiReadoutBinder alongside.

Behaviour:

• No focus state, no LOD overrides, no overlay-held flag.
• Each baked body fires with ContentMode::Value at the LOD the body itself baked in (per-call lod= option, default Lod::Labeled).
• Multiple bodies bound to the same slot fire in order (the composition rule from SRD-63 §5.5).

Implementations

impl DefaultBinder

pub fn new() -> Self

pub fn bind(&mut self, event: EventType, body: BakedBody)

Bind a baked body to an event slot. Multiple calls with the same event append in order.

pub fn set(&mut self, event: EventType, body: BakedBody)

Replace whatever’s at this slot with a single body — Form A / B’s “scalar means single-element list” path.

pub fn slot_len(&self, event: EventType) -> usize

Number of bodies bound to this slot. 0 means the event will fire and produce no output — surfaces expecting a default render need to seed builtins before calling fire.

pub fn merge(&mut self, other: DefaultBinder)

Drain other’s bindings into self, appending each body to its slot. Used by the CLI-override resolver to combine the workload-+-default-resolved binder with a CLI-supplied extra body.

pub fn unbind(&mut self, event: EventType)

Drop every body bound to event. Surfaces that want “no readouts at this slot” call this rather than binding an empty body.

pub fn take_bodies(&mut self, event: EventType) -> Vec<BakedBody>

Remove and return the resolved bodies bound to event, leaving the slot empty. SRD-100 P2 — the executor extracts the resolved on_update template from a freshly-built binder to attach to the live render handle (PhaseRenderHandle::bodies), so the consumer can fire it with &self without holding the !Sync binder.

Trait Implementations

impl Default for DefaultBinder

fn default() -> Self

Returns the “default value” for a type.

impl ReadoutBinder for DefaultBinder

fn fire( &mut self, event: EventType, ctx: &dyn ReadoutContext, sink: &mut dyn ReadoutSink, )

Drive every readout bound to event. The binder applies its interactive state, walks the resolved list, and emits render steps to sink.

fn on_key(&mut self, _key: BinderKey)

Forward a keyboard event from the surface. Default no-op for non-interactive sinks.
