Struct BackendTolerance

Expand description

Backend-specific tolerance configuration

Implements Poka-Yoke (mistake-proofing) by providing compile-time guarantees for correct tolerance values per backend type.

Fields§

§scalar_vs_simd: f32

Scalar vs SIMD tolerance (should be exact: 0.0)

§simd_vs_gpu: f32

SIMD vs GPU tolerance (IEEE 754: 1e-5)

§gpu_vs_gpu: f32

GPU vs GPU tolerance (same precision: 1e-6)
