Function `dmd.func.MODMatchToBuffer`

Checks for mismatching modifiers between lhsMod and rhsMod and prints the mismatching modifiers to buf.


						
				dmd.func.MODMatchToBuffer MODMatchToBuffer
				(
				

				  scope OutBuffer* buf,
				

				  ubyte lhsMod,
				

				  ubyte rhsMod
				

				);

The modifiers of the lhsMod mismatching the ones with the rhsMod are printed, i.e. lhs(shared) vs. rhs() prints "shared", wheras lhs() vs rhs(shared) prints "non-shared".

Parameters

Name	Description
buf	output buffer to write to
lhsMod	modifier on the left-hand side
lhsMod	modifier on the right-hand side

Returns

A tuple with isMutable and isNotShared set if the lhsMod is missing those modifiers (compared to rhs).

Example

OutBuffer buf;
auto mismatches = MODMatchToBuffer(&buf, MODFlags.shared_, 0);
writeln(buf[]); // "`shared` "
assert(!mismatches.isNotShared);

buf.setsize(0);
mismatches = MODMatchToBuffer(&buf, 0, MODFlags.shared_);
writeln(buf[]); // "non-shared "
assert(mismatches.isNotShared);

buf.setsize(0);
mismatches = MODMatchToBuffer(&buf, MODFlags.const_, 0);
writeln(buf[]); // "`const` "
assert(!mismatches.isMutable);

buf.setsize(0);
mismatches = MODMatchToBuffer(&buf, 0, MODFlags.const_);
writeln(buf[]); // "mutable "
assert(mismatches.isMutable);
