number-general

A generic Rust number type with support for basic math operations, (de)serialization, and casting with safecast.

Example usage:

use number_general::{Int, Number};
use safecast::CastFrom;

let sequence: Vec<Number> = serde_json::from_str("[true, 2, 3.5, -4, [1.0, -0.5]]").unwrap();
let actual = sequence.into_iter().product();

assert_eq!(actual, Number::from(num::Complex::<f64>::new(-28., 14.)));
assert_eq!(Int::cast_from(actual), Int::from(-28));

lib.rs:

Provides a generic Number enum with Boolean, Complex, Float, [Int], and UInt variants, as well as a NumberCollator, ComplexCollator, and FloatCollator since these types do not implement [Ord].

Number supports casting with safecast.

For (de)serialization with serde, enable the "serde" feature.

For (de)coding with destream, enable the "stream" feature.

Example usage:

let sequence: Vec<Number> = vec![true.into(), 2.into(), 3.5.into(), [1.0, -0.5].into()];
let actual = sequence.into_iter().product();
let expected = Number::from(num::Complex::<f64>::new(7., -3.5));

assert_eq!(expected, actual);
assert_eq!(Int::cast_from(actual), Int::from(7));
