fixed_len_str

This Rust library provides a procedural macro for declare a wrapper struct for an array with the size given by the tokens which dereferences to str and a macro for create they from str.

For a proper API documentation of one of length 12 see fixed_len_str_example.

Usage

use fixed_len_str::fixed_len_str;

fixed_len_str!(3);

fn main() {
    let string = new_str3!("abc");
    
    assert_eq!(string, "abc");
    
    let string = FixedStr3::new(*b"abc");
    
    assert_eq!(string, "abc");
    
    let mut string = FixedStr3::default(); // equivalent to mem::zeroed but safe
    string.fill_zeroes_str("abc");
    
    assert_eq!(string, "abc");
    
    let mut string = FixedStr3::new([b'a', b'b', 0]);
    string.fill_zeroes_char('c');
    
    assert_eq!(string, "abc");
    assert_eq!(string.as_bytes(), string.as_ref().as_bytes());
    assert_eq!(string.clone().into_string(), String::from(string.as_ref()));
