File.write("file.sz", Bytes[255, 6, 0, 0, 115, 78, 97, 80, 112, 89, 1, 8, 0, 0, 104, 16, 130, 162, 97, 98, 99, 100])

string = File.open("file.sz") do |file|
   Compress::Snappy::Reader.open(file) do |sz|
     sz.gets_to_end
   end
end
string # => "abcd"

Example: compress a file to snappy format

require "snappy"

File.write("file.txt", "abcd")

File.open("./file.txt", "r") do |input_file|
  File.open("./file.sz", "w") do |output_file|
    Compress::Snappy::Writer.open(output_file) do |sz|
      IO.copy(input_file, sz)
    end
