String.Chars protocol
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)
.
