Ocaml_utils.CompressionSourceCompression.output_value chan v writes the representation of v on channel chan. If compression is supported, the marshaled data representing value v is compressed before being written to channel chan. If compression is not supported, this function behaves like Stdlib.output_value.
Compression.input_value chan reads from channel chan the byte representation of a structured value, as produced by Compression.output_value, and reconstructs and returns the corresponding value. If compression is not supported, this function behaves like Stdlib.input_value.
Reports whether compression is supported.
