Expand description

A method declaration inside a schema’s with { ... } block.

Source form: [#derive C ...]* [#native] name(p1: T1, ...) -> R [: body] — the body is required when is_native is false and forbidden when it is true (parser enforces this).

Fields§

§name: String

Method name (the name in name(...) -> R).

§name_range: TokenRange§generics: Vec<String>

Method-level generic type parameter names (e.g. ["U"] for map<U>(...)). Empty for monomorphic methods. Each occurrence inside params[i].type_node or return_type is a placeholder instantiated at the call site, on top of any schema-level placeholders already in scope.

§params: Vec<SchemaMethodParam>

Typed parameters as written; self is implicit and is added by the analyzer when lowering.

§return_type: TypeNode

Return type (the R in -> R). Required for every method — methods are not type-inferred at the signature level.

§body: Option<Box<Node>>

Body expression (: body). None when the method is marked #native — the host registers the implementation.

§derives: Vec<String>

Constraint names from method-level #derive <Constraint> pragmas, in source order.

§is_native: bool

True when an #native pragma precedes this method, indicating the body lives in host Rust (registered via the schema-method host API). The parser leaves body None in this case.

§is_private: bool

True when a #internal pragma precedes this method. Internal methods are visible only from other method bodies on the same schema; script-level value.method() calls fail with MethodNotFound at the analyzer stage.

§range: TokenRange§doc_comment: Option<String>
