# IO wrapper that creates digests of contents written to the IO it wraps.

class Gem::Package::DigestIO

##
  # Collected digests for wrapped writes.

##
  # Wraps +io+ and updates digest for each of the digest algorithms in
  # the +digests+ Hash.  Returns the digests hash.  Example:
  #
  #   io = StringIO.new
  #   digests = {
  #     'SHA1'   => OpenSSL::Digest.new('SHA1'),
  #     'SHA512' => OpenSSL::Digest.new('SHA512'),
  #   }
  #
  #   Gem::Package::DigestIO.wrap io, digests do |digest_io|
  #     digest_io.write "hello"
  #   end
  #
  #   digests['SHA1'].hexdigest   #=> "aaf4c61d[...]"
  #   digests['SHA512'].hexdigest #=> "9b71d224[...]"
