...Match statements are very flexible and structural in nature
Instead of nesting match statements, for example, one could bring values together as tuples and do
the following:
fn player_outcome(player: &Move, opp: &Move) -> Outcome {
use Move::*;
use Outcome::*;
match (player, opp) {
// Rock moves.
(Rock, Rock) => Draw,
(Rock, Paper) => Lose...
...And then you always have like a else match case, like what to do when none of the other matches match.
I assume you would use it with enums a lot, right?
Where you have like multiple.
Options within your enum and you essentially just want to like go through...
pub fn unwrap(self) -> T...Instead, prefer to use the ? (try) operator, or pattern matching to handle the Err case explicitly, or call unwrap_or, unwrap_or_else, or unwrap_or_default.
Panics
Panics if the value is an Err, with a panic message provided by the Err's value.
