I am trying to send attachment inside email from my phoenix application using Bamboo. Library used: nimble_csv bamboo bamboo_smtp The attachment is in-memory data that I am getting after parsing the CSV and making some changes into it. I don’t want to save the CSV file so using the in-memory ap…

How can I do that can you please help me with that? Sorry that was lame question below method did the trick. def convert_to_binary(data) do data |> IO.iodata_to_binary end Thanks.

You can simply use the to_string function.

I could be wrong, but I think to_string is not equivalent to IO.iodata_to_binary. to_string expects a list of codepoints, but IO.iodata_to_binary expects any integers in the list to be bytes: iex(2)> "hełło" |> String.to_charlist |> IO.iodata_to_binary ** (ArgumentError) argument error :erlang.…

Interesting nuance. It’s just that I very early learned to use to_string on iolists and kind of never questioned it because it always worked well (and without botching encoding).

Gotcha. If I had to guess, IO.iodata_to_binary is gonna perform better because it only needs to concern itself with bytes.

You need to pass in a binary, rather than iodata.
