Tuples & Destructuring
Tuples in Rust are a bit easier to use than their C++ cousins. In C++:
std::tuple<std::string, double> tuple = {"Hello", 3.14};
let s = std::get<0>(tuple);
let n = std::get<1>(tuple);
In Rust, you can define a tuple with parentheses:
fn main() { let tuple = ( "Hello".to_string(), 3.14 ); let n = tuple.1; }
Rust also supports destructuring:
fn main() { let tuple = { "Hello".to_string(), 3.14 }; let (name, value) = tuple; }
