Structs

Scope

Functions

current_scope

scope_memo

Access the current Scope’s memo cache (Scope::memo). The value lives until that Scope is disposed (navigation pop, root shutdown) - not merely until a scope! cache key stops composing, since scope! is a memo cache, not a Scope.

scoped_effect

Scoped effect that auto-cleans up.

scoped_effect_once

Mount-once scoped effect: runs f only the first time this call site composes, registering cleanup on the current scope. Later recompositions are no-ops. Requires composition context.
