Struct InvokerScope
pub struct InvokerScope(/* private fields */);Expand description
The invoker whose resource tree a delivered invocation resolves against, for the duration of its resolution and dispatch on this thread.
Resource collection for resolution
([crate::widget::Widget::resources_for]) and view operations read it,
so an invocation is resolved against the invoker’s own view, rebuilt at
invoke time, never against a published snapshot. Scopes nest; dropping
the guard restores the enclosing invoker.
