Enum SimdTier 

#[non_exhaustive]
pub enum SimdTier {
    Unknown,
    CurrentHost,
    Wasm,

}

SIMD instruction tier the codec will dispatch to. Optional hint on ComputeEnvironment — a wider/newer tier generally means faster encode/decode, so estimates can apply a per-tier time factor. Variants mirror the x86-64-vN microarchitecture levels and the archmage / magetypes token vocabulary, so an archmage-detected tier maps trivially.

use zenpixels_convert::{ComputeEnvironment, SimdTier};
let tier = if archmage::X64V4Token::summon().is_some() { SimdTier::X86V4 }
    else if archmage::X64V3Token::summon().is_some() { SimdTier::X86V3 }
    else if archmage::X64V2Token::summon().is_some() { SimdTier::X86V2 }
    else { SimdTier::X86V1 };
let env = ComputeEnvironment::new().with_cores(8).with_simd_tier(tier);

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.

Unknown

SIMD tier unknown. Currently treated as the AVX2 calibration baseline (multiplier 1.0) — there is no separate conservative cross-tier model yet; one lands with the per-tier calibration sweep (see the TODO on estimate_plan). Use CurrentHost for the local machine.

CurrentHost

Host running the estimate (≈ calibration host’s native tier). Distinct from Unknown which is a cross-tier average.

Wasm

WebAssembly, no SIMD128 (scalar wasm).

Wasm128

WebAssembly SIMD128.

Neon

AArch64 / ARM NEON (archmage NeonToken).

X86V1

x86-64-v1 — SSE2 baseline.

X86V2

x86-64-v2 — SSE4.2 (archmage X64V2Token).

X86V3

x86-64-v3 — AVX2 + FMA (archmage X64V3Token).

X86V4

x86-64-v4 — AVX-512 (archmage X64V4Token).
