Execution-mode markers for SIMD operations.

Two ZST markers define whether a crate::view::SimdView operates on all lanes (dense) or a hardware-predicated subset (masked). The sealed ExecutionMode trait prevents external implementations and enables the compiler to eliminate dead mode branches via DCE during monomorphization.

§Design

  • Unmasked — default; maps to unconditional arithmetic. Zero overhead vs. not parameterizing by mode at all.
  • Masked — activates predicated methods on SimdView. Maps to AVX-512 mask registers (__mmask16/__mmask8), AVX2 blend masks (__m256), SVE predicates, or scalar [bool; N] arrays depending on the bound SimdKernel implementation.

Structs§

Masked
Predicated execution — a hardware mask selects active lanes.
Unmasked
Dense execution — all lanes are active. Default mode for crate::view::SimdView.

Traits§

ExecutionMode
Marker trait for SIMD execution modes.
