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.
• Supports AoS/SoA/AoSoA via Real::as_simd/Real::as_simd_mut abstracting over as_simd/as_simd_mut of f32 and f64 slices.
• 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.
