Struct IntegerRange 

pub struct IntegerRange { /* private fields */ }

An integer range value provider.

Efficiently provides a contiguous range of integers without storing them.

Implementations

impl IntegerRange

pub fn new(start: i64, end: i64) -> Self

Creates a new integer range [start, end).

pub fn from_zero(n: i64) -> Self

Creates a range from 0 to n (exclusive).

pub fn value_range_type(&self) -> ValueRangeType

Returns the ValueRangeType describing this range.

An IntegerRange is a countable range with known bounds.

Trait Implementations

impl<S> ValueRangeProvider<S, i32> for IntegerRange

where S: Send + Sync,

fn get_values(&self, _solution: &S) -> Vec<i32>

Returns all possible values for the variable.

fn value_count(&self, _solution: &S) -> usize

Returns the number of possible values.

fn is_empty(&self, solution: &S) -> bool

Returns whether the value range is empty.
