rustHow do I access a tuple variable by index in Rust?
You can access a tuple variable by index in Rust using the . operator. For example:
let my_tuple = (1, 2, 3);
let first_element = my_tuple.0;This will set first_element to 1.
Code explanation
let my_tuple = (1, 2, 3);: This creates a tuple with three elements.let first_element = my_tuple.0;: This accesses the first element of the tuple and assigns it to the variablefirst_element.
