class FunctionSignature

FunctionSignature(name: str, parameters: tuple[ParameterSpec, ...], return_type: astx.DataType, calling_convention: CallingConvention, is_variadic: bool = False, is_extern: bool = False, exception_abi: bool = True, symbol_name: str = '', required_runtime_features: tuple[str, ...] = (), ffi: FFICallableInfo | None = None, metadata: dict[str, Any] = dict(), operation: CallOperation | None = None)

Canonical semantic callable signature.

Normalize the stable callable contract that semantic analysis resolves and lowering consumes.

Attributes

• name — Type: str

• parameters — Type: tuple[ParameterSpec, Ellipsis]

• return_type — Type: astx.DataType

• calling_convention — Type: CallingConvention

• is_variadic — Type: bool

• is_extern — Type: bool

• exception_abi — Type: bool; Generated functions return status and receive context plus a typed output slot for non-none results. Externs retain their declared ABI.

• symbol_name — Type: str

• required_runtime_features — Type: tuple[str, Ellipsis]

• ffi — Type: FFICallableInfo | None

• metadata — Type: dict[str, Any]

• operation — Type: CallOperation | None
