Type Definition generic_str::ArrayString

pub type ArrayString<const N: usize> = OwnedString<u8, [MaybeUninit<u8>; N]>;

Same API as String but without any re-allocation. Can only hold up to N bytes

let mut s = ArrayString::<8>::new();
assert_eq!(std::mem::size_of_val(&s), 8 + 8); // 8 bytes of storage, 8 bytes for length

s.push_str("foo".into());
let t = s.clone(); // cloning requires no heap allocations
s.push_str("bar".into());

assert_eq!(t, <&str>::from("foo"));
assert_eq!(s, <&str>::from("foobar"));

Implementations

impl<const N: usize> ArrayString<N>

pub fn new() -> Self

Creates a new empty ArrayString.

Examples

Basic usage:

let s = ArrayString::<8>::new();
