Work on zstd started in July 2025. The first milestone is the decompression portion of the library.

Now the decompression is in development, we're seeking funding for the encoder. Please get in touch with us, if you are interested in financially supporting the development of memory-safe zstd.

In progress milestones

Milestone 1: Decoder

  • decoder Publish a crate to crates.io that contains the C interface, and a C dynamic library for zstd decompression that is API-compatible.

Milestone 2: dictBuilder

  • Implementation of the dictBuilder feature
  • Deliverable: release of the zstd-rs library (libzstd-rs-sys) including the dictBuilder feature

Future work

Milestone 3: Encoder

  • encoder Adds API-compatible zstd compression.
