Expand description

The equivalent of SliceIndex for RawStr.

Usage

Normally, this trait is not used directly. Its functionality is exposed through Index and the get methods of RawStr.

Implementors

RawStrIndex is automatically implemented for all that implement SliceIndex<[u8]>:

a SliceIndex<[u8], Output=[u8]> automatically implements RawStrIndex<Output=RawStr>, and
a SliceIndex<[u8], Output=u8> automatically implements RawStrIndex<Output=u8>.

Examples

let s = RawStr::from_str("hello world");
let hello: &RawStr = &s[..5]; // This is a slice.
let space: u8 = s[5]; // This is a single byte
assert_eq!(hello, "hello");
assert_eq!(space, b' ');
