View Source String.Chars protocol (Elixir v1.18.0)
The String.Chars protocol is responsible for
converting a structure to a binary (only if applicable).
The only function required to be implemented is
to_string/1, which does the conversion.
The to_string/1 function automatically imported
by Kernel invokes this protocol. String
interpolation also invokes to_string/1 in its
arguments. For example, "foo#{bar}" is the same
as "foo" <> to_string(bar).
