Function `std.encoding.codeUnits`

Returns a foreachable struct which can bidirectionally iterate over all code units in a code point.


						
				CodeUnits!E codeUnits(E)
				(
				

				  dchar c
				

				);

The input to this function MUST be a valid code point. This is enforced by the function's in-contract.

The type of the output cannot be deduced. Therefore, it is necessary to explicitly specify the encoding type in the template parameter.

Supersedes

This function supersedes std.utf.encode().
