@spec function!(module(), atom() | String.t()) :: RustQ.Rust.AST.Function.t()

Returns one generated defrust function AST by name, raising when absent.

@spec functions(module()) :: [RustQ.Rust.AST.Function.t()]

Returns all generated defrust function AST nodes from a compiled module.

Raises ArgumentError when the module does not contain compiled defrust metadata.

@spec functions!(module(), [atom() | String.t()]) :: [RustQ.Rust.AST.Function.t()]

Returns selected generated defrust function AST nodes.

@spec macro_call!(module(), atom() | String.t(), keyword()) ::
  RustQ.Rust.AST.MacroItemCall.t()

Builds a structural invocation of a generated Rust item macro.

@spec macro_item!(module(), atom() | String.t()) :: RustQ.Rust.AST.MacroItem.t()

Returns one generated defrustmacro item AST by name, raising when absent.

@spec macro_items!(module(), [atom() | String.t()]) :: [RustQ.Rust.AST.MacroItem.t()]

Returns selected generated defrustmacro item AST nodes.

@spec struct_type_items(module(), [atom()], keyword()) :: [RustQ.Rust.AST.Struct.t()]

Builds Rust struct items for selected map-backed @type declarations.

Use :derive, :attrs, and :vis to adapt the structural type item at a boundary such as Rustler encoding without duplicating its fields.
