gruel_parser::ast

Struct InterfaceDecl

pub struct InterfaceDecl {
    pub doc: Option<Doc>,
    pub directives: Directives,
    pub visibility: Visibility,
    pub name: Ident,
    pub methods: Vec<MethodSig>,
    pub span: Span,
}

Expand description

An interface declaration (ADR-0056).

Interfaces are structurally typed sets of method requirements. A type conforms to an interface iff its method set covers every method signature required here.

interface Drop {
    fn __drop(self);
}

Fields§

§doc: Option<Doc>

ADR-0089: docstring attached to this interface.

§directives: Directives

Directives applied to this interface (e.g., @lang("drop")).

§visibility: Visibility

Visibility (currently always private; module-system support is future work).

§name: Ident

Interface name

§methods: Vec<MethodSig>

Required method signatures, in declaration order. The order is significant: it determines vtable slot indices in the runtime dispatch path (Phase 4).

§span: Span

Span covering the entire interface declaration
