Trait encode_unicode::U8UtfExt [−] [src]

pub trait U8UtfExt {
    fn extra_utf8_bytes(self) -> Result<usize, InvalidUtf8FirstByte>;
    fn extra_utf8_bytes_unchecked(self) -> usize;
}

Methods for working with u8s UTF-8.

Required Methods

`fn extra_utf8_bytes(self) -> Result<usize, InvalidUtf8FirstByte>`

How many more bytes will you need to complete this codepoint? Failures:

128..192: ContinuationByte
240..: TooLongSequence

`fn extra_utf8_bytes_unchecked(self) -> usize`

How many more bytes will you need to complete this codepoint? Assumes that self is a valid UTF-8 start. Returns self.not().leading_zeros().saturating_sub(1)
