Module dispatch 

Runtime SIMD feature detection and dispatch. Runtime SIMD feature detection and function-pointer dispatch.

On first access the best available SIMD level is detected via CPUID (x86_64) or compile-time knowledge (aarch64, where NEON is mandatory). The result is cached in a OnceLock so subsequent calls are a single pointer load.

Structs

SimdOps

Function-pointer table for the three core SIMD operations.

Enums

SimdLevel

Supported SIMD instruction set level, ordered from least to most capable.

Functions

detect

Detect the best SIMD level supported by the current CPU at runtime.

ops

Return a reference to the auto-detected SimdOps dispatch table.
