Struct ScopeFrame

pub struct ScopeFrame {
    pub overlays: Vec<(Vec<u8>, OverlayFrame)>,
    pub active_overlays: Vec<OverlayId>,
    pub removed_overlays: Vec<Vec<u8>>,
    pub predecls: HashMap<Vec<u8>, DeclId>,
}

Fields

overlays: Vec<(Vec<u8>, OverlayFrame)>

List of both active and inactive overlays in this ScopeFrame.

The order does not have any meaning. Indexed locally (within this ScopeFrame) by OverlayIds in active_overlays.

active_overlays: Vec<OverlayId>

List of currently active overlays.

Order is significant: The last item points at the last activated overlay.

removed_overlays: Vec<Vec<u8>>

Removed overlays from previous scope frames / permanent state

predecls: HashMap<Vec<u8>, DeclId>

temporary storage for predeclarations
