Struct RangeTo

pub struct RangeTo {
    pub end: Value,
}

Type for an inclusive range expression ..end.

Examples

let range = ..10;
assert!(range.contains(-10));
assert!(range.contains(5));
assert!(!range.contains(10));
assert!(!range.contains(20));

assert!(range is std::ops::RangeTo);

Ranges can contain any type:

let range = ..'f';
assert_eq!(range.end, 'f');
range.end = 'g';
assert_eq!(range.end, 'g');

Examples

use rune::runtime::RangeTo;

let end = rune::to_value(1)?;
let _ = RangeTo::new(end);

Fields

end: Value

The end value of the range.

Implementations

impl RangeTo

pub fn new(end: Value) -> Self

Construct a new range.

pub fn partial_eq(&self, other: &Self) -> VmResult<bool>

Test the range for partial equality.

Examples

let range = ..'e';
assert!(range == (..'e'));
assert!(range != (..'f'));

let range = ..2.0;
assert!(range == (..2.0));
assert!(range != (..f64::NAN));
assert!((..f64::NAN) != (..f64::NAN));

pub fn eq(&self, other: &Self) -> VmResult<bool>

Test the range for total equality.

Examples

use std::ops::eq;

let range = ..'e';
assert!(eq(range, ..'e'));
assert!(!eq(range, ..'f'));

pub fn partial_cmp(&self, other: &Self) -> VmResult<Option<Ordering>>

Test the range for partial ordering.

Examples

assert!((..'a') < (..'b'));
assert!((..'d') > (..'b'));
assert!(!((..f64::NAN) > (..f64::INFINITY)));
assert!(!((..f64::NAN) < (..f64::INFINITY)));

pub fn cmp(&self, other: &Self) -> VmResult<Ordering>

Test the range for total ordering.

Examples

use std::ops::cmp;
use std::cmp::Ordering;

assert_eq!(cmp(..'a', ..'b'), Ordering::Less);
assert_eq!(cmp(..'c', ..'b'), Ordering::Greater);
