Struct TabHandle 

pub struct TabHandle {
    pub id: TabId,
    pub info: TabInfo,
    pub kind: &'static str,
    pub payload: Rc<dyn Any>,
}

One tab’s identity, presentation, and state pointer.

Clone is cheap: TabInfo is shallow (the icon is an Rc<dyn Fn() -> IconWidget> factory) and payload is an Rc<dyn Any>.

Fields

id: TabId

info: TabInfo

kind: &'static str

payload: Rc<dyn Any>

Implementations

impl TabHandle

pub fn dynamic<S: Any + 'static>( id: TabId, kind: &'static str, info: TabInfo, state: S, ) -> Self

Construct a handle for the dynamic-tab path. The kind must match a dynamic_tab::<S> registration on the TabWidget where this handle lands; the framework downcasts payload to S before calling the registered factory and panics with a clear message on type mismatch.

pub fn dynamic_shared( id: TabId, kind: &'static str, info: TabInfo, payload: Rc<dyn Any>, ) -> Self

Construct a handle for the dynamic-tab path with a pre-built Rc<dyn Any> payload — useful when several handles share the same underlying state object.
