along an axis.
end: S
The end of some Range
along an axis.
Implementations
Construct a new Range
from a given range, i.e. Range::new(start, end)
.
Examples
use nannou::geom::Range;
assert_eq!(Range { start: 0.0, end: 10.0 }, Range::new(0.0, 10.0));
Construct a new Range
from a given length and its centered position.
Examples
use nannou::geom::Range;
assert_eq!(Range::new(0.0, 10.0), Range::from_pos_and_len(5.0, 10.0));
assert_eq!(Range::new(-5.0, 1.0), Range::from_pos_and_len(-2.0, 6.0));
assert_eq!(Range::new(-100.0, 200.0), Range::from_pos_and_len(50.0, 300.0));
The start
value subtracted from the end
value.
Examples
use nannou::geom::Range;
assert_eq!(Range::new(-5.0, 5.0).magnitude(), 10.0);
assert_eq!(Range::new(5.0, -5.0).magnitude(), -10.0);
assert_eq!(Range::new(15.0, 10.0).magnitude(), -5.0);
The absolute length of the Range aka the absolute magnitude.
Examples
use nannou::geom::Range;
assert_eq!(Range::new(-5.0, 5.0).len(), 10.0);
assert_eq!(Range::new(5.0, -5.0).len(), 10.0);
assert_eq!(Range::new(15.0, 10.0).len(), 5.0);
Return the value directly between the start and end values.
Examples
use nannou::geom::Range;
assert_eq!(Range::new(-5.0, 5.0).middle(), 0.0);
assert_eq!(Range::new(5.0, -5.0).middle(), 0.0);
assert_eq!(Range::new(10.0, 15.0).middle(), 12.5);

Examples
use nannou::geom::Range;
assert_eq!(Range::new(-5.0, 5.0).invert(), Range::new(5.0, -5.0));
assert_eq!(Range::new(-10.0, 10.0).invert(), Range::new(10.0, -10.0));

to some other given Range
.
Examples
use nannou::geom::Range;
let a = Range::new(0.0, 5.0);
let b = Range::new(0.0, 10.0);
assert_eq!(a.map_value(2.5, &b), 5.0);
assert_eq!(a.map_value(0.0, &b), 0.0);

let c = Range::new(10.0, -10.0);
assert_eq!(a.map_value(2.5, &c), 0.0);
assert_eq!(a.map_value(0.0, &c), 10.0);
assert_eq!(a.map_value(5.0, &c), -10.0);
assert_eq!(a.map_value(-5.0, &c), 30.0);
assert_eq!(a.map_value(10.0, &c), -30.0);
Interpolates the Range using the given weight
.
Examples
use nannou::geom::Range;
let r = Range::new(-5.0, 5.0);
assert_eq!(r.lerp(0.0), -5.0);
assert_eq!(r.lerp(1.0), 5.0);
assert_eq!(r.lerp(0.5), 0.0);
Shift the Range
start and end points by a given scalar.
Examples
use nannou::geom::Range;
assert_eq!(Range::new(0.0, 5.0).shift(5.0), Range::new(5.0, 10.0));
assert_eq!(Range::new(0.0, 5.0).shift(-5.0), Range::new(-5.0, 0.0));
assert_eq!(Range::new(5.0, -5.0).shift(-5.0), Range::new(0.0, -10.0));
The direction of the Range represented as a normalised scalar.
Examples
use nannou::geom::Range;
assert_eq!(Range::new(0.0, 5.0).direction(), 1.0);
assert_eq!(Range::new(0.0, 0.0).direction(), 0.0);
assert_eq!(Range::new(0.0, -5.0).direction(), -1.0);
Converts the Range to an absolute Range by ensuring that start
<= end
.
If start
> end
, then the start and end points will be swapped.
Examples
use nannou::geom::Range;
assert_eq!(Range::new(0.0, 5.0).absolute(), Range::new(0.0, 5.0));
assert_eq!(Range::new(5.0, 1.0).absolute(), Range::new(1.0, 5.0));
assert_eq!(Range::new(10.0, -10.0).absolute(), Range::new(-10.0, 10.0));
The Range that encompasses both self and the given Range.
The returned Range’s start
will always be <= its end
.
Examples
use nannou::geom::Range;
let a = Range::new(0.0, 3.0);
let b = Range::new(7.0, 10.0);
assert_eq!(a.max(b), Range::new(0.0, 10.0));
let c = Range::new(-20.0, -30.0);
let d = Range::new(5.0, -7.5);
assert_eq!(c.max(d), Range::new(-30.0, 5.0));
The Range that represents the range of the overlap between two Ranges if there is some.
Note that If one end of self
aligns exactly with the opposite end of other
, Some
Range
will be returned with a magnitude of 0.0
. This is useful for algorithms that
involve calculating the visibility of widgets, as it allows for including widgets whose
bounding box may be a one dimensional straight line.
The returned Range
’s start
will always be <= its end
.
Examples
use nannou::geom::Range;
let a = Range::new(0.0, 6.0);
let b = Range::new(4.0, 10.0);
assert_eq!(a.overlap(b), Some(Range::new(4.0, 6.0)));
let c = Range::new(10.0, -30.0);
let d = Range::new(-5.0, 20.0);
assert_eq!(c.overlap(d), Some(Range::new(-5.0, 10.0)));
let e = Range::new(0.0, 2.5);
let f = Range::new(50.0, 100.0);
assert_eq!(e.overlap(f), None);
The Range that encompasses both self and the given Range.
The same as Range::max but retains self
’s original
direction.
Examples
use nannou::geom::Range;
let a = Range::new(0.0, 3.0);
let b = Range::new(7.0, 10.0);
assert_eq!(a.max_directed(b), Range::new(0.0, 10.0));
let c = Range::new(-20.0, -30.0);
let d = Range::new(5.0, -7.5);
assert_eq!(c.max_directed(d), Range::new(5.0, -30.0));

assert!(range.contains(0.0));
assert!(range.contains(10.0));

Examples

assert_eq!(Range::new(0.25, 9.5).round(), Range::new(0.0, 10.0));
