Struct regex_syntax::ClassRange

pub struct ClassRange {
    pub start: char,
    pub end: char,
}

A single inclusive range in a character class.

Since range boundaries are defined by Unicode scalar values, the boundaries can never be in the open interval (0xD7FF, 0xE000). However, a range may cover codepoints that are not scalar values.

Note that this has a few convenient impls on PartialEq and PartialOrd for testing whether a character is contained inside a given range.

Fields

start: char

The start character of the range.

This must be less than or equal to end.

end: char

The end character of the range.

This must be greater than or equal to start.
