ClassScope

Struct ClassScope 

Source
pub struct ClassScope<'a> {
    pub tree: &'a ItemTree,
    pub base: Ty,
    pub self_ty: Ty,
    pub member_types: FxHashMap<SmolStr, Ty>,
    /* private fields */
}
Expand description

The class-member tier of the binder (Playbook §3.2 step 2): this file’s own members + the resolved base type. Anonymous-enum variants are flattened in as int constants.

Fields§

§tree: &'a ItemTree

The lowered item tree this scope describes.

§base: Ty

The resolved base type (Object(id) for an engine base, else Unknown).

§self_ty: Ty

The static type of self in this class’s bodies. Defaults to base, but analyze_file overrides it with the script’s own Ty::ScriptRef so that member access on an aliased self (var me := self; me.own_method()) walks the file’s own members instead of only the engine base — otherwise a real own-method call would false-warn UNSAFE_METHOD_ACCESS. (Direct self.member already uses the own-member fast path.)

§member_types: FxHashMap<SmolStr, Ty>

Resolved types of this class’s own fields (var/const), seeded by a first inference pass over the field initializers so member references see the inferred type (e.g. var n := 0int), not just the annotation. Empty until populated.

Implementations§
