Struct regex_syntax::hir::ClassUnicodeRange
source · pub struct ClassUnicodeRange {
start: char,
end: char,
}
Expand description
A single range of characters represented by Unicode scalar values.
The range is closed. That is, the start and end of the range are included in the range.
Fields§
§start: char
§end: char
Implementations§
source§impl ClassUnicodeRange
impl ClassUnicodeRange
sourcepub fn new(start: char, end: char) -> ClassUnicodeRange
pub fn new(start: char, end: char) -> ClassUnicodeRange
Create a new Unicode scalar value range for a character class.
The returned range is always in a canonical form. That is, the range
returned always satisfies the invariant that start <= end
.
sourcepub fn start(&self) -> char
pub fn start(&self) -> char
Return the start of this range.
The start of a range is always less than or equal to the end of the range.
