Package zstd holds zstd encoders and decoders used by the GAE library.
DecodeAll allows stateless decoding of a blob of bytes.
Output will be appended to dst, so if the destination size is known you can pre-allocate the destination slice to avoid allocations. DecodeAll can be used concurrently.
EncodeAll will encode all input in src and append it to dst.
This function can be called concurrently, but each call will only run on a single goroutine. If empty input is given, nothing is returned. Data compressed with EncodeAll can be decoded via DecodeAll.
