fixedlenstr

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].

Usage

```rust use fixedlenstr::fixedlenstr;

fixedlenstr!(3);

fn main() { let string = new_str3!("abc");

assert_eq!(string.as_ref(), "abc");

let string = FixedStr3::new(*b"abc");

assert_eq!(string.as_ref(), "abc");

let mut string = FixedStr3::default(); // equivalent to mem::zeroed but safe
string.fill_zeroes_str("abc");

assert_eq!(string.as_ref(), "abc");

let mut string = FixedStr3::new([b'a', b'b', 0]);
string.fill_zeroes_char('c');

assert_eq!(string.as_ref(), "abc");

} ```
