List.Chars protocol (Elixir v1.12.2) View Source

The List.Chars protocol is responsible for converting a structure to a charlist (only if applicable).

The only function that must be implemented is to_charlist/1 which does the conversion.

The to_charlist/1 function automatically imported by Kernel invokes this protocol.
