movavg - Generic Moving Average calculation

https://bues.ch/

Generic Moving Average calculation for the integer types

• i8, i16, i32, i64, i128, isize
• u8, u16, u32, u64, u128, usize

and float types

• f32, f64

Usage

Add this to your Cargo.toml:

[dependencies]
movavg = 1.0

Example usage:

// Integers
let mut avg: MovAvg<i32> = MovAvg::new(3); // window size = 3
assert_eq!(avg.feed(10), 10);
assert_eq!(avg.feed(20), 15);
assert_eq!(avg.feed(30), 20);
assert_eq!(avg.feed(40), 30);

// Floats
let mut avg: MovAvg<f64> = MovAvg::new(3);
assert_eq!(avg.feed(10.0), 10.0);
assert_eq!(avg.feed(20.0), 15.0);
assert_eq!(avg.feed(30.0), 20.0);
assert_eq!(avg.feed(40.0), 30.0);

// Bigger accumulator
let mut avg: MovAvg<i8, i32> = MovAvg::new(3);
assert_eq!(avg.feed(100), 100);
assert_eq!(avg.feed(100), 100); // This would overflow an i8 accumulator
