Crate lav

Lane-Associated Vector (LAV): Portable SIMD vector trait as GAT of SIMD lane trait.

NOTE: This crate requires nightly Rust.

Features

• SIMD lane trait Real abstracting over f32 and f64.
• SIMD vector trait SimdReal<Real, N> abstracting over Simd<f32, N> and Simd<f64, N>.
• Generic associated type (GAT) Real::Simd<N> as part of SIMD lane trait Real implementing SIMD vector trait SimdReal<Self, N> for itself as lane type where the GAT is generic over the number of SIMD vector lanes N.
• Lanewise approximate equality test wrt to epsilon and ULP SIMD vectors.
• ApproxEq trait complementing PartialEq.
• no_std without loss of functionality by enabling the libm feature.

This example uses SIMD generically over floating-point types while hiding it from the user.

Modules

• example
  Portably SIMD-optimized 3D rotator implementation generic over lane type f32 and f64.

Macros

• swizzle
  Constructs vector by copying lanes from selected lanes of one or two input vectors.

Traits

• ApproxEq
  Tests for approximate equality.
• Bits
  Bits representation of Real number with associated SimdBits vector.
• Real
  Real number of f32 or f64 with associated Bits representation and SimdReal vector.
• Select
  Selects lanes from two vectors by mask vector.
• SimdBits
  Bits representation vector of SimdReal vector with associated SimdMask vector.
• SimdMask
  Mask vector of Mask<i32, N> or Mask<i64, N>.
• SimdReal
  Real number vector of Simd<f32, N> or Simd<f64, N> with associated SimdBits and SimdMask vector.
