namenf

The namefn crate provides a flag for retrieving the name of a function. Use the #[name] flag to get the function name. You can access the name via the NAME variable. The name is a &str, by default. This crate is extremely useful for logging and other tracking purposes.

Example

The basic functionality consists of getting the functions name via a const variable called NAME.

```Rust use namefn::name;

[namefn]

fn main() { assert_eq!("main", NAME); } ```

You can also crate a custom function name:

```Rust use namefn::name;

[namefn(alias = "cool_name")]

fn uncoolname() { asserteq!("cool_name", NAME); } ```

Here the name is cool_name instead of uncool_name.

If you for some reason already have a constant called name you can also rename the constant.

```Rust use namefn::name;

[namefn(const = FUNCTION)]

fn main() { assert_eq!("main", FUNCTION); } ```

The name is still main but the constant is now called FUNCTION.

Note: If the const attribute is lowercase it will be converted to uppercase.
