ReflectedFn

struct ReflectedFn[func_type: AnyType, //, func: func_type]

A compile-time reflection handle type for a function value.

All methods are @staticmethod — the handle has no runtime state, only compile-time parameters. Spell access as reflect_fn[func].display_name() (preferred) or ReflectedFn[func].display_name().

Example:

from std.reflection import reflect_fn

def my_func(x: Int) -> Int:
    return x

def main():
    print(reflect_fn[my_func].display_name())  # "my_func"

Parameters​

  • ​func_type (AnyType): The function's type. Inferred from func.
  • ​func (func_type): The function value being introspected.

Implemented traits​

AnyType, ImplicitlyDestructible

Methods​

display_name​

static display_name() -> StaticString

Returns the function's name as declared in source.

The returned name does not include any information about the function's parameters, arguments, or return type.

Example:

def my_func(): pass
print(reflect_fn[my_func].display_name())  # "my_func"

Returns:

StaticString: The function's source-level name.

linkage_name​

static linkage_name[*, target: __mlir_type.`!kgen.target` = _current_target()]() -> StaticString

Returns the function's mangled linkage / symbol name.

Parameters:

  • ​target (__mlir_type.`!kgen.target`): The compilation target (defaults to the current target).

Returns:

StaticString: The symbol name as it appears in the linker.
