Module sessions 

Host-side typed handles for the generated act:sessions/session-provider bindings.

act-world declares session-provider as an export, but it is opt-in: stateless components do not export it. The host therefore binds it through a per-interface GuestIndices::new lookup that is allowed to fail — instantiate_component turns that failure into None, so components without session-provider instantiate fine.

Session, Error and Metadata come straight from the generated bindings (the same act:core/types records the tool-provider uses, shared via the single act-world bindgen invocation).

Structs

Session

act:sessions/types.session — re-exported from the generated bindings so callers keep referring to sessions::Session. Component-side state container.

SessionProvider

Typed handles to the three session-provider functions of one component instance, derived from the generated session Guest.
