Function `std.range.primitives.popBack`

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


						
				void popBack(T)
				(
				

				  scope ref inout(T)[] a
				

				) pure nothrow @nogc @safe
				

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

				

				void popBack(T)
				(
				

				  scope ref inout(T)[] a
				

				) pure @safe
				

				if (isNarrowString!(T[]));

Example

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