Struct IntervalSet 

pub struct IntervalSet { /* private fields */ }

Ordered set of integer intervals used by set and negated-set transitions.

Unicode grammars can contain very large ranges, so this stores normalized intervals rather than expanding every code point into a flat set.

Implementations

impl IntervalSet

pub fn new() -> Self

pub fn from_range(start: i32, stop: i32) -> Self

pub fn add(&mut self, value: i32)

pub fn add_range(&mut self, start: i32, stop: i32)

Adds an inclusive interval and merges it with adjacent or overlapping intervals.

pub fn contains(&self, value: i32) -> bool

Returns true when value falls inside any stored interval.

pub fn ranges(&self) -> &[(i32, i32)]

pub const fn is_empty(&self) -> bool

Trait Implementations

impl Clone for IntervalSet

fn clone(&self) -> IntervalSet

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IntervalSet

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for IntervalSet

fn default() -> IntervalSet

Returns the “default value” for a type.

impl PartialEq for IntervalSet

fn eq(&self, other: &IntervalSet) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
