Function `std.typecons.Tuple.opEquals`

Comparison for equality. Two Tuples are considered equal iff they fulfill the following criteria:


						
				bool opEquals(R)
				(
				

				  R rhs
				

				)
				

				if (areCompatibleTuples!(typeof(this), R, "=="));
				

				

				bool opEquals(R)
				(
				

				  R rhs
				

				) const
				

				if (areCompatibleTuples!(typeof(this), R, "=="));
				

				

				bool opEquals(R...)
				(
				

				  auto ref R rhs
				

				)
				

				if (R.length > 1 && areCompatibleTuples!(typeof(this), Tuple!R, "=="));

Each Tuple is the same length.
For each type T on the left-hand side and each type U on the right-hand side, values of type T can be compared with values of type U.
For each value v1 on the left-hand side and each value v2 on the right-hand side, the expression v1 == v2 is true.

Parameters

Name	Description
rhs	The `Tuple` to compare against. It must meeting the criteria for comparison between `Tuple`s.

Returns

true if both Tuples are equal, otherwise false.

Example

Tuple!(int, string) t1 = tuple(1, "test");
Tuple!(double, string) t2 =  tuple(1.0, "test");
//Ok, int can be compared with double and
//both have a value of 1
writeln(t1); // t2
