1 Introduction

This is an FFI binding for the Snappy library from Google. Snappy provides very fast compression and decompression, though with larger compressed sizes.

procedure
(compress input) → bytes?
input : bytes?

Compresses the input bytestring and returns the resulting bytestring.

procedure
(uncompress input) → bytes?
input : (and/c bytes? valid-compression?)

Uncompresses the input bytestring and returns the resulting bytestring. Requires that the input bytestring was the result of a valid Snappy compression.

procedure
(valid-compression? input) → boolean?
input : bytes?

Returns #t if input is a compressed bytestring that can be uncompressed with Snappy. Otherwise returns #f.
