Function `rt.aApply._aApplydc1`

Loop over a string while changing the UTF encoding


						
				extern(C) int _aApplydc1(
				
  scope const(dchar)[] aa,
				
  int delegate(void*) dg
				

				);

There are 6 combinations of conversions between char, wchar, and dchar, and 2 of each of those.

The naming convention is as follows:

aApply{c,d,w}{c,d,w}{1,2}

The first letter corresponds to the input string encoding, and the second letter corresponds to the target character type.

- c = char - w = wchar - d = dchar

The 1 variant only produces the character, the 2 variant also produces a loop index.

Examples

void main()
{
    string str;
    wtring wstr;
    dstring dstr;

    foreach (dchar c; str) {}
    // _aApplycd1

    foreach (wchar c; dstr) {}
    // _aApplydw1

    foreach (i, wchar c; str) {}
    // _aApplycw2

    foreach (wchar w; wstr) {}
    // no conversion
}

Parameters

Name	Description
aa	input string
dg	foreach body transformed into a delegate, similar to `opApply`

Returns

non-zero when the loop was exited through a break
