Struct SimdCapabilities 

pub struct SimdCapabilities {
    pub avx2: bool,
    pub avx512: bool,
    pub neon: bool,
}

CPU SIMD capabilities.

This structure represents the SIMD instruction sets available on the current CPU, detected at runtime.

Fields

avx2: bool

x86 AVX2 support (Intel Haswell 2013+, AMD Excavator 2015+).

avx512: bool

x86 AVX-512 support (Intel Skylake-X 2017+, Ice Lake 2019+).

neon: bool

ARM NEON support (all ARMv8/AArch64, ARMv7-A with NEON).

Implementations

pub const fn has_avx512(&self) -> bool

Check if AVX-512 is available.

pub const fn has_neon(&self) -> bool

Check if NEON is available.

pub const fn best_level(&self) -> &'static str
