pulp 0.22.0

//! `pulp` is a safe abstraction over SIMD instructions, that allows you to write a function once
//! and dispatch to equivalent vectorized versions based on the features detected at runtime.
//!
//! # Autovectorization example
//!
//! ```
//! use pulp::Arch;
//!
//! let mut v = (0..1000).map(|i| i as f64).collect::<Vec<_>>();
//! let arch = Arch::new();
//!
//! arch.dispatch(|| {
//! 	for x in &mut v {
//! 		*x *= 2.0;
//! 	}
//! });
//!
//! for (i, x) in v.into_iter().enumerate() {
//! 	assert_eq!(x, 2.0 * i as f64);
//! }
//! ```
//!
//! # Manual vectorization example
//!
//! ```
//! use pulp::{Arch, Simd, WithSimd};
//!
//! struct TimesThree<'a>(&'a mut [f64]);
//! impl<'a> WithSimd for TimesThree<'a> {
//! 	type Output = ();
//!
//! 	#[inline(always)]
//! 	fn with_simd<S: Simd>(self, simd: S) -> Self::Output {
//! 		let v = self.0;
//! 		let (head, tail) = S::as_mut_simd_f64s(v);
//!
//! 		let three = simd.splat_f64s(3.0);
//! 		for x in head {
//! 			*x = simd.mul_f64s(three, *x);
//! 		}
//!
//! 		for x in tail {
//! 			*x = *x * 3.0;
//! 		}
//! 	}
//! }
//!
//! let mut v = (0..1000).map(|i| i as f64).collect::<Vec<_>>();
