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 end.

Trait Implementations

impl Ord for ClassRange

fn cmp(&self, __arg_0: &ClassRange) -> Ordering

This method returns an Ordering between self and other.

impl Eq for ClassRange

impl PartialOrd for ClassRange

fn partial_cmp(&self, __arg_0: &ClassRange) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, __arg_0: &ClassRange) -> bool

This method tests less than (for self and other) and is used by the < operator.

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, __arg_0: &ClassRange) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl PartialEq for ClassRange

fn eq(&self, __arg_0: &ClassRange) -> bool
