Function `std.range.primitives.popFront`

Implements the range interface primitive popFront for built-in arrays. Due to the fact that nonmember functions can be called with the first argument using the dot notation, array.popFront is equivalent to popFront(array). For narrow strings, popFront automatically advances to the next code point.


						
				void popFront(T)
				(
				

				  scope ref inout(T)[] a
				

				) pure nothrow @nogc @safe
				

				if (!isNarrowString!(T[]) && !is(T[] == void[]));
				

				

				void popFront(C)
				(
				

				  scope ref inout(C)[] str
				

				) pure nothrow @trusted
				

				if (isNarrowString!(C[]));

Example

auto a = [ 1, 2, 3 ];
a.popFront();
writeln(a); // [2, 3]
