Struct WidgetEnv 

pub struct WidgetEnv<'a> {
    pub caches: &'a ExtensionCaches,
    pub ctx: RenderCtx<'a>,
}

Context provided to extension render() methods.

All fields are immutable references – mutation happens in prepare(), reads happen here. This mirrors iced’s update()/view() split.

Available data

• caches – extension caches (read-only). Use caches.get::<T>(config_key, node_id) to read per-node state populated in prepare().
• ctx – the shared RenderCtx carrying images, theme, defaults, and child rendering. Convenience methods below delegate to it: images(), theme(), default_text_size(), default_font(), render_child().

Fields

caches: &'a ExtensionCaches

ctx: RenderCtx<'a>
