Expand description

Creates a decoder iterator over UTF-32 encoded code points in iter, returning invalid values as Errs.

Examples

use widestring::decode_utf32;

// 𝄞mus<invalid>ic<invalid>
let v = [
    0x1D11E, 0x6d, 0x75, 0x73, 0xDD1E, 0x69, 0x63, 0x23FD5A,
];

assert_eq!(
    decode_utf32(v.iter().copied())
        .map(|r| r.map_err(|e| e.invalid_code_point()))
        .collect::<Vec<_>>(),
    vec![
        Ok('𝄞'),
        Ok('m'), Ok('u'), Ok('s'),
        Err(0xDD1E),
        Ok('i'), Ok('c'),
        Err(0x23FD5A)
    ]
