Infinity for types without infinite values

Infinitable introduces the notion of “infinity” and “negative infinity” to numeric types, such as integers, that do not have infinite values.

A representation of infinity is useful for graph algorithms such as Dijkstra’s algorithm, as well as for representing a graph with an adjacency matrix.

Basic Usage

use infinitable::*;

let finite = Finite(5);
let infinity = Infinity;
let negative_infinity = NegativeInfinity;

assert!(finite < infinity);
assert!(finite > negative_infinity);

Re-exports

Enums

Infinitable

An “infinitable” value, one that can be either finite or infinite

Functions

from_f32

Converts from f32 value to an optional Infinitable<f32>, accounting for floating-point infinities and NaN.

from_f64

Converts from f64 value to an optional Infinitable<f64>, accounting for floating-point infinities and NaN.
