Enum HostClass 

pub enum HostClass {
    X86_64Avx512,
    X86_64Avx2,
    X86_64Scalar,
    Aarch64Apple,
    Aarch64,
    Generic,
}

The class of the machine, keyed by the kernel dispatch it will take, not by the CPU model. Detected once per process by HostClass::detect.

The same enum and the same detect are kept in sync by hand in strided-rs, tcontract-rs and faer’s cost tables: each crate owns a table of its own kernels keyed by this class.

Variants

X86_64Avx512

x86_64 with AVX-512F at run time (x86_64-avx512).

X86_64Avx2

x86_64 with AVX2 and FMA, without AVX-512F (x86_64-avx2).

X86_64Scalar

Any other x86_64 (x86_64-scalar).

Aarch64Apple

aarch64 on macOS (aarch64-apple).

Aarch64

Any other aarch64 (aarch64).

Generic

Everything else (generic).

Implementations

impl HostClass

pub fn detect() -> Self

The class of this host, detected at the first call and cached (OnceLock; is_x86_feature_detected! on x86_64).

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

The class name used in the docs and the tables: x86_64-avx512, x86_64-avx2, x86_64-scalar, aarch64-apple, aarch64, generic.
