Encoding method

These are different methods for COBS encoding. They all produce the same output, but have different runtime characteristics.

Variants

Trivial

Simple loop, sequentially processing every byte without (explicitly) using SIMD instructions.

Crazy

Direct translation of unhinged C implementation from wikipedia

Simd16

Optimized version which uses an iterator producing blocks that internally uses SIMD intrinsics for finding zeros in the data.

StdSimd8

Versions that use std::Simd operations to be generic over vector length

StdSimd16

StdSimd32

StdSimd8TwoStage

Versions that use std::Simd operations to be generic over vector length and separate the zero-finding and splitting of large blocks, which may yield a small performance benefit

StdSimd16TwoStage

StdSimd32TwoStage
