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.

threadteam::HostClass re-exported, so the enum and its detect are the ones the placement token uses and cannot drift from them. The upstream doc below still names strided-rs among the crates that keep a hand-synced copy; this crate no longer does.

Compatibility

This is a type-identity change, not a rename: strided_perm::HostClass is now the same type as threadteam::HostClass instead of a distinct copy. A downstream crate that implemented its own trait for both types compiles against the old pair and fails with E0119 (conflicting implementations) against this one. Code that names the type, compares it, or matches on its variants is unaffected. 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.

Implementations

impl HostClass

pub fn detect() -> HostClass

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.
