Compress()

size_t casacore::deflate::Compressor::Compress ( std::span< const std::byte >  input, std::span< std::byte >  output  )

inline

Compresses the input into output.

If the compressed data does not fit into output, a value of zero is returned. Otherwise, the number of output bytes written is returned.
