API Docs

Example

Add positions as a dependency of your project.

[dependencies]
positions = "0.1"

# `rust_decimal` is added to make the example code work,
# but optional for using `positions`.
rust_decimal = "1.17.0"
rust_decimal_macros = "1.17.0"

And then, you can try these codes.

use positions::normal;
use rust_decimal_macros::dec;

let h1 = normal((dec!(1.0), dec!(2.0)));
let h2 = normal((dec!(2.0), dec!(3.0)));
let h3 = normal((dec!(1.5), dec!(-4.0)));

assert_eq!(h1 + h2 + h3, normal((dec!(1.6), dec!(1.0), dec!(-0.4))));
