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 | One byte range. |
Two | Two successive byte ranges. |
Three | Three successive byte ranges. |
Four | Four successive byte ranges. |
Methods
impl Utf8Sequence
fn as_slice(&self) -> &[Utf8Range]
Returns the underlying sequence of byte ranges as a slice.
fn len(&self) -> usize
Returns the number of byte ranges in this sequence.
The length is guaranteed to be in the closed interval [1, 4].
fn matches(&self, bytes: &[u8]) -> bool
Returns true if and only if a prefix of bytes matches this sequence
of byte ranges.
