lav

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

NOTE: This crate requires nightly Rust.

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

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.
• 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.

Optional Features

Following features are disabled by default unless their feature gate is enabled:

• target-features: Provides native number of SIMD vector lanes Real::NATIVE_LANE_COUNT for the current build target.
• libm: Enables no_std without loss of functionality.
