@asserttranscode(ZstdDecompressor, compressed) ==Vector{UInt8}(text)This package exports following codecs and streams:
| Codec | Stream |
|---|---|
ZstdCompressor | ZstdCompressorStream |
ZstdDecompressor | ZstdDecompressorStream |
Version 0.8.3 also introduced the virtual codec ZstdFrameCompressor which stores the decompressed content size in the frame header. Currently, ZstdFrameCompressor is an alternate constructor for ZstdCompressor, but that is an implementation detail which should not be relied upon.
See docstrings and TranscodingStreams.jl for details.
