Derive Macro FieldNames 

#[derive(FieldNames)]

Generates methods for retrieving field names of a struct as string literals.

This function is used as part of a procedural macro. It takes a struct definition, extracts its named fields, and generates a method for each field. Each generated method follows the naming pattern nameof_<field_name>(), which returns the field name as a static string.

Example

use quick_macros::FieldNames;

#[derive(FieldNames)]
struct Person {
    name: String,
    age: u32,
}

assert_eq!(Person::nameof_name(), "name");
assert_eq!(Person::nameof_age(), "age");

Panics

• If the macro is applied to a non-struct type (e.g., an enum or union), it will panic.
