Struct Interval 

pub struct Interval {
    pub lo: i64,
    pub hi: i64,
}

A closed integer interval [lo, hi].

Fields

lo: i64

Lower bound (inclusive).

hi: i64

Upper bound (inclusive).

Implementations

impl Interval

pub fn new(lo: i64, hi: i64) -> Self

Create an interval.

pub fn point(x: i64) -> Self

A single-element interval.

pub fn contains(&self, x: i64) -> bool

Whether x is in the interval.

pub fn is_empty(&self) -> bool

Whether the interval is empty (lo > hi).

pub fn len(&self) -> u64

Length of the interval.

pub fn intersect(&self, other: &Interval) -> Interval

Intersect with another interval.

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

Union with another interval (assumes overlapping or adjacent).

pub fn decide_contains(&self, x: i64) -> Decision<()>

Decide whether x is in the interval.

Trait Implementations

impl Clone for Interval

fn clone(&self) -> Interval

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Interval

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

Formats the value using the given formatter.

impl Display for Interval

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

Formats the value using the given formatter.

impl PartialEq for Interval

fn eq(&self, other: &Interval) -> 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.
