BitConverter

BitConverter is a library that provides a straightforward and convenient way to encode and decode binaries. It encapsulates bitstring syntax and Erlang's :binary module functions for encoding and decoding within an easy-to-use API.

Installation

The package can be installed by adding bit_converter to your list of dependencies in mix.exs:

def deps do
  [
    {:bit_converter, "~> 0.1.0"}
  ]
end

Run mix deps.get in your console to fetch from Hex.

Usage

# decoding
iex> BitConverter.decode_uint16(<<255, 255>>)
65535

iex> BitConverter.decode_int16(<<255, 127>>)
32_767

iex> BitConverter.decode_uint32(<<255, 255, 255, 255>>)

# encoding
iex> BitConverter.encode_uint16(65535)
<<255, 255>>

iex> BitConverter.encode_int16(32_767)
<<255, 127>>

iex> BitConverter.encode_uint32(4_294_967_295)
