Struct IntervalSet 

pub struct IntervalSet { /* private fields */ }

A normalized set of inclusive code-point intervals.

Implementations

impl IntervalSet

pub fn new(intervals: &[(u32, u32)]) -> Self

Normalize and build from possibly overlapping, unordered intervals.

pub fn empty() -> Self

The empty set.

pub fn full() -> Self

Every code point.

pub fn single(code_point: u32) -> Self

A set holding one code point.

pub fn from_range(low: u32, high: u32) -> Self

An inclusive range, clamped to the Unicode bounds.

pub fn from_normalized(intervals: Vec<(u32, u32)>) -> Self

Build from already-normalized intervals without re-checking.

pub fn intervals(&self) -> &[(u32, u32)]

The normalized interval list.

pub fn is_empty(&self) -> bool

Whether the set holds no code points.

pub fn contains(&self, code_point: u32) -> bool

Binary-search membership.

pub fn first_member(&self) -> Option<u32>

The smallest member, if any.

pub fn component_first_members(&self) -> Vec<u32>

The first member of every component interval.

pub fn member_count(&self) -> u64

The total number of code points in the set.

pub fn union(&self, other: &IntervalSet) -> IntervalSet

Union (concatenate then renormalize).

pub fn intersection(&self, other: &IntervalSet) -> IntervalSet

Sweep-line intersection.

pub fn complement(&self) -> IntervalSet

Every code point not in the set.

pub fn difference(&self, other: &IntervalSet) -> IntervalSet

Members of self not in other.
