[−][src]Function oner_quantize::quantize
pub fn quantize<A, C>(
intervals: &[Interval<A, C>],
attribute_value: A
) -> Option<&Interval<A, C>> where
A: PartialOrd + Copy,
C: Copy,
Find which interval applies to a given attribute value.
Examples
use oner_quantize::Interval; use oner_quantize::quantize; let intervals = vec![ Interval::lower(15, "x"), Interval::range(15, 20, "y"), Interval::upper(20, "z") ]; // Quantize into an interval, and extract the corresponding class: let class = |attribute_value| quantize(&intervals, attribute_value) .map(|interval| interval.class()); assert_eq!(class(10), Some(&"x")); assert_eq!(class(15), Some(&"y")); assert_eq!(class(99), Some(&"z"));
