Function Closures

This crate allows you to create constant functions, and the identity function and combine them with a couple basic operations like follows

// for graphing this is y = x
let y = Function::default();

// f(x) = 3x
let f = Function::new(3.)*Function::default();

// note that Function implements From::<f64> no matter the underlying type
let f = Function::from(3.)*Function::default();

Development

Development is currently very active and many breaking changes are still to come

docs


lib.rs:

This library allows you to do three things. It allows you to Create a function that returns a constant f(x) -> 4, create a function that returns its input f(x) -> x, and then do arithmatic with them and store the result f(x) -> x, g(x) -> 4, h = fg => h ~= 4x then you can do whatever you want with the resulting Arc<Fn(T) -> T> where T is essentially an f64 or other similar type
