Enum utf8_ranges::Utf8Sequence [] [src]

pub enum Utf8Sequence {
    One(Utf8Range),
    Two([Utf8Range; 2]),
    Three([Utf8Range; 3]),
    Four([Utf8Range; 4]),
}

Utf8Sequence represents a sequence of byte ranges.

To match a Utf8Sequence, a candidate byte sequence must match each successive range.

For example, if there are two ranges, [C2-DF][80-BF], then the byte sequence \xDD\x61 would not match because 0x61 < 0x80.

Variants

One byte range.

Two successive byte ranges.

Three successive byte ranges.

Four successive byte ranges.

Methods

impl Utf8Sequence
[src]

Returns the underlying sequence of byte ranges as a slice.

Returns the number of byte ranges in this sequence.

The length is guaranteed to be in the closed interval [1, 4].

Returns true if and only if a prefix of bytes matches this sequence of byte ranges.
