Method usage example
use yata::prelude::*;
use yata::methods::EMA;
// EMA of length=3
let mut ema = EMA::new(3, &3.0).unwrap();
ema.next(&3.0);
ema.next(&6.0);
assert_eq!(ema.next(&9.0), 6.75);
assert_eq!(ema.next(&12.0), 9.375);
Indicator usage example
use yata::helpers::{RandomCandles, MA};
use yata::indicators::MACD;
use yata::prelude::*;
let mut candles = RandomCandles::new();
let mut macd = MACD::default();
macd.method1 = "sma-4".parse().unwrap(); // one way of defining methods inside indicators
macd.signal = MA::TEMA(5); // another way of defining methods inside indicators
let mut macd = macd.init(&candles.first()).unwrap();
for candle in candles.take(10) {
let result = macd.next(&candle);
println!("{:?}", result);
}

Current unsafe status
By default, there is no unsafe code in the crate. But you can optionally enable unsafe_performance feature throw you Cargo.toml or by --feature flag in your CLI.
unsafe_performance enables some unsafe code blocks, most of them are unsafe access to a vector's elements. For some methods it may increase performance by ~5-10%.
Features
serde- enablesserdecrate support;period_type_u16- setsPeriodTypetou16;period_type_u32- setsPeriodTypetou32;period_type_u64- setsPeriodTypetou64;value_type_f32- setsValueTypetof32;unsafe_performance- enables optional unsafe code blocks, which may increase performance;
Rust version
YaTa library supports Rust stable except that you can't run benchmarks with it.
