Trait ReferenceRenderer 

pub trait ReferenceRenderer {
    // Required method
    fn render_reference(
        &mut self,
        ui: &mut Ui,
        field: &FormField,
        filter: &[String],
        multiple: bool,
        current: &mut Value,
        probe: Option<&mut HashMap<String, Rect>>,
    ) -> (bool, Rect);
}

The engine-agnostic seam for a REAL reference-selection widget. field_input stays free of any engine dependency (a later brep-ui crate reuses it verbatim); a caller that CAN pick — the feature dialog, which holds &mut EngineState — passes a &mut dyn ReferenceRenderer and field_input delegates each FieldKind::Reference field to it. When no renderer is supplied (the settings panel, which has no reference fields) it falls back to the inert placeholder.

Required Methods

fn render_reference( &mut self, ui: &mut Ui, field: &FormField, filter: &[String], multiple: bool, current: &mut Value, probe: Option<&mut HashMap<String, Rect>>, ) -> (bool, Rect)

Draw the COLLAPSED reference field — an activation button plus the current selection listed one-per-line, each line with an X to remove it. Returns (changed, activation_button_rect): changed is true when a name was removed (so the caller commits the edited current back to the engine). probe, when present, receives the activation + per-line-X widget rects (keyed "<path>#activate", "<path>#x<index>") for the headed verifier.

Dyn Compatibility

This trait is dyn compatible.

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