func_

Proc macro to insert function name within body of function because Rust is incapable of doing simple things

Once type_name is stable in const context this macro can be replaced properly with simple function call on function type.

Usage

use func_::_func_;

#[_func_]
fn my_func() {
    assert_eq!(__func__, "my_func");
}

Proc macro to insert function name within body of function

Usage

use func_::_func_;

#[_func_]
fn my_func() {
    assert_eq!(__func__, "my_func");

    println!("{__func__}: log with function name");
}

#[_func_]
fn my_generic_func<T>() {
    assert_eq!(__func__, "my_generic_func");

    println!("{__func__}: log with generic function name but without generics bullshit cuz why the would I want generics in my generic name?");
}

#[_func_]
const fn const_func() {
    assert!(__func__.len() == "const_func".len());
}

#[_func_]
async fn async_func() {
    assert_eq!(__func__, "async_func");
}

my_func();
my_generic_func::<u16>();
const_func();
