Elixir v1.3.0 String.Chars protocol View Source
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
which does the conversion.
The to_string
function automatically imported
by Kernel invokes this protocol. String
interpolation also invokes to_string
in its
arguments. For example, "foo#{bar}"
is the same
as "foo" <> to_string(bar)
.
