Enum regex_syntax::utf8::Utf8Sequence
source · pub enum Utf8Sequence {
One(Utf8Range),
Two([Utf8Range; 2]),
Three([Utf8Range; 3]),
Four([Utf8Range; 4]),
}
Expand description
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(Utf8Range)
One byte range.
Two([Utf8Range; 2])
Two successive byte ranges.
Three([Utf8Range; 3])
Three successive byte ranges.
Four([Utf8Range; 4])
Four successive byte ranges.
Implementations§
source§impl Utf8Sequence
impl Utf8Sequence
sourcepub fn as_slice(&self) -> &[Utf8Range]
pub fn as_slice(&self) -> &[Utf8Range]
Returns the underlying sequence of byte ranges as a slice.
sourcepub fn len(&self) -> usize
pub 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]
.
