ZstdCompressor(;level=3)

Create a new zstd compression codec.

Arguments

• level: compression level (1..22)

ZstdCompressorStream(stream::IO; kwargs...)

Create a new zstd compression stream (see ZstdCompressor for kwargs).

ZstdDecompressor()

Create a new zstd decompression codec.

ZstdDecompressorStream(stream::IO; kwargs...)

Create a new zstd decompression stream (kwargs are passed to TranscodingStream).

ZstdFrameCompressor(;level=3)

Create a new zstd compression codec that reads the available input and then closes the frame, encoding the decompressed size of that frame.

Arguments

• level: compression level (1..22)

compress!(cstream::CStream; endOp=:continue)

Compress a Zstandard CStream. Optionally, provide one one of the following end directives

• :continue - (default) collect more data, encoder decides when to output compressed result, for optimal compression ratio
• :flush - flush any data provided so far
• :end - flush any remaining data and close current frame

If :end is provided on the first call to compress!, the size of the input data will be recorded in the frame header. This is equivalent to calling CodecZstd.LibZstd.ZSTD_compress2. See also CodecZstd.LibZstd.ZSTD_CCtx_setPledgedSrcSize.
