fixedlenstr

This Rust library provides a procedural macro for declare a wrapper struct for an array with the size given by the tokens which derefs to [str].

For a proper API documentation of one of length 12 see [fixedlenstr_example].

If you want to use [serde] to serialize and deserialize the fixedlenstr use features = ["serde_support"],if you want to match a pattern of type FnMut(FixedStr$len) -> bool on a [str] use features = ["pattern_pred_support"] and if you want the documentation visible at the expansion use default-features = false.

Usage

```rust use fixedlenstr::fixedlenstr;

fixedlenstr!(3);

fn main() { let string = FixedStr3::from("abc");

assert_eq!(string, "abc");

let string = unsafe { FixedStr3::new_unchecked(*b"abc") };

assert_eq!(string, "abc");

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

assert_eq!(string, "abc");

let mut string = unsafe { FixedStr3::new_unchecked([b'a', b'b', 0]) };
assert_eq!(string, "ab");
string.fill_char('c');

assert_eq!(string, "abc");
assert_eq!(string.as_bytes(), (&string[..]).as_bytes()); // this is only certain with non-zero bytes
assert_eq!(string.into_string(), String::from(&string[..])); // clone or consume at your option
assert_eq!(FixedStr3::from(&[][..]), "");

if cfg!(feature = "pattern_pred_support") {
    use fixed_str3::Closure; // needed due to the orphan rule

    assert_eq!("aaabb".matches(Closure::from(|s: FixedStr3| s == "aaa" || s == "bb"))
                      .collect::<Vec<&str>>(), ["aaa", "bb"]);
}

} ```
