Rust Tuples
Introduction
The most trivial data-structure, after a singular value, is the tuple.
Syntax
- (A, B, C) // a three-tuple (a tuple with three elements), whose first element has type A, second type B, and third type C
- (A, B) // a two-tuple, whose two elements have type A and B respectively
- (A,) // a one-tuple (note the trailing
,), which holds only a single element of type A - () // the empty tuple, which is both a type, and that type's only element
