Hi everyone Im facing problems with bitstrings I’m open a folder containing files and have to encode it with Huffman algorithm( huffman | Hex ), after encoding I have to save it into an encripted file, but the Huffman.encode functions returns an encoded bitstring and not a binary so I cant save it due…

The biggest difference between a bitstring and a binary is that the former isn’t evenly divisible into bytes - you need to decide how to pad your data (leading zeros? trailing zeros?) to a multiple of 8 bits.

You’ll problably need to store the number of bits padded in the file as well, otherwise you won’t be able to reconstruct the original bitstring from the file. Small example t = <<3::size(17)>> # => <<0, 1, 1::size(1)>> pad = 8 - (bit_size(t) - (bit_size(t) |> Integer.floor_div(8)) * 8) # => 7 <<…
