This crate provides procedural macrs to generate functions that return static slices of struct field names or enum variant names.

Examples

use fievar::Fields;

#[derive(Fields)]
struct Token {
    access_token: String,
    refresh_token: String,
}

assert_eq!(&["access_token", "refresh_token"], Token::fields());

You can also rename fields.

use fievar::Fields;

#[derive(Fields)]
struct Token {
    #[fievar(name = "accessToken")]
    access_token: String,
    refresh_token: String,
}

assert_eq!(&["accessToken", "refresh_token"], Token::fields());
