Scroll's DA encoding/decoding libraries.

go test -v -race ./...

Q: Why the repo contains libscroll_zstd*.a binary files?

A: This simplifies package installation with go get without the need to perform additional steps for building the libscroll_zstd*.a.

Q: Which platforms/architectures are supported?

A: linux/amd64, linux/arm64, darwin/arm64. Pull requests for other platforms/architectures are accepted.

Q: I don't trust libscroll_zstd*.a binary files from the repo or these files don't work on my OS/ARCH. How to rebuild them?

A: To rebuild the libraries for your platform:

1. Build the legacy encoder:

   cd libzstd/encoder-legacy
   make install

2. Build the standard encoder:

   cd libzstd/encoder-standard
   make install

3. Add symbol prefixes to avoid conflicts:

   cd encoding/zstd
   ./add_symbol_prefix.sh

   Note: The symbol prefix script currently only works on macOS. For Linux builds, perform steps 1-2 in Docker, then run step 3 on macOS.

   For macOS builds, ensure you have Rust and necessary build tools installed:

   # Install Rust if not already installed
   curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

   For Linux builds, use Docker with build dependencies:

   # Linux ARM64
   docker run -it --rm --platform linux/arm64 -v $(pwd):/workspace -w /workspace rust:1.75-slim bash
   apt update && apt install -y build-essential
   
   # Linux AMD64
   docker run -it --rm --platform linux/amd64 -v $(pwd):/workspace -w /workspace rust:1.75-slim bash
   apt update && apt install -y build-essential
