Enum MaxSimIsa 

#[non_exhaustive]
pub enum MaxSimIsa {
    Auto,
    Scalar,
    X86_64_V3,
    X86_64_V4,
    Neon,
    Reference,
}

Instruction Set Architecture (ISA) selector for which multi-vector MaxSim kernel to build.

#[non_exhaustive] so adding a variant (e.g. for a new in-tree kernel) is not a breaking change. Deliberately not Serialize/Deserialize — callers wanting JSON support maintain their own shadow enum and convert via From / TryFrom, so the library is not pinned to a particular serialization format.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Auto

Pick the highest ISA the host CPU supports.

Scalar

Pure-scalar (emulated SIMD) kernel — always available.

X86_64_V3

x86_64 AVX2 + FMA.

X86_64_V4

x86_64 AVX-512.

Neon

AArch64 Neon.

Reference

Non-SIMD reference fallback. Slow; serves as a correctness baseline.

Implementations

impl MaxSimIsa

pub fn is_available(self) -> bool

Whether a kernel for this ISA can be built on the current host. Feature-gated variants may return false even when compiled for the matching target architecture.

Trait Implementations

impl Clone for MaxSimIsa

fn clone(&self) -> MaxSimIsa

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for MaxSimIsa

impl Debug for MaxSimIsa

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for MaxSimIsa

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for MaxSimIsa

impl Hash for MaxSimIsa

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MaxSimIsa

fn eq(&self, other: &MaxSimIsa) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
