Struct Utf8Chunks

struct Utf8Chunks<'a> { ... }

An iterator used to decode a slice of mostly UTF-8 bytes to string slices ([&str]) and byte slices (&[u8]).

This struct is created by the utf8_chunks method on bytes slices. If you want a simple conversion from UTF-8 byte slices to string slices, from_utf8 is easier to use.

See the Utf8Chunk type for documentation of the items yielded by this iterator.

Examples

This can be used to create functionality similar to String::from_utf8_lossy without allocating heap memory:

fn from_utf8_lossy<F>(input: &[u8], mut push: F) where F: FnMut(&str) {
    for chunk in input.utf8_chunks() {
        push(chunk.valid());

        if !chunk.invalid().is_empty() {
            push("\u{FFFD}");
        }
    }
}
