Reduce unnecessary Vec allocations and indirections #77

merged 1 commit into from Sep 3, 2022

Commits on Aug 28, 2022

  1. Reduce unnecessary allocations and indirections 

    * Changed literal_probs array from a Vec<Vec<u16>> to a Vec2D backed by a contiguous allocation
* BitTrees in LenDecoder and DecoderState are now stored inline. The actual BitTree data still
  lives in a Vec but one level of indirection is reduced.
* Don't bother with filling stack-allocated DecoderState arrays on reset, and just recreate the
  arrays dropping the existing ones.
