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
Add this to your Cargo.toml:
[dependencies]
movavg = "2"
// Integers
let mut avg: MovAvg<i32, i32, 3> = MovAvg::new(); // 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);
assert_eq!(avg.get(), 30);
// Floats
let mut avg: MovAvg<f64, f64, 3> = MovAvg::new();
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);
assert_eq!(avg.get(), 30.0);
// Bigger accumulator
let mut avg: MovAvg<i8, i32, 3> = MovAvg::new();
assert_eq!(avg.feed(100), 100);
assert_eq!(avg.feed(100), 100); // This would overflow an i8 accumulator
If you want to use movavg without the std library (often called no_std), then use the following Cargo.toml dependency to disable the std feature:
[dependencies]
movavg = { version = "2", default-features = false }
Currently the no_std variant supports all functionality that the default std variant supports. But that may change in future.
The fastfloat feature can be used to enable much faster, but less accurate floating point calculations. Enabling this feature leads to bigger floating point rounding and cancellation errors.
[dependencies]
movavg = { version = "2", features = ["fastfloat"] }
This feature may also be used together with disabled std feature (see no_std).
Requires Rust compiler version 1.61 or later.
