Dude wtf is your problem don’t just leave things lying about there don’t you know how to code I mean what the- I don’t go to your house and leave shit on the floor and just—
sometimes you need an unused variable. some uses in rust:
// destructuringlet (width, _height) = get_dimensions();
// trait implementations (i couldnt think of a better example for this)implIntoforAlwaysZero {
fninto(_value: Self) -> {
return0;
}
}
// some types (eg. Result) must be 'used'// assigned to a variable if we dont care about the return valuelet_ = returns_result("foo");
int unused_variable = 0;int _unused_variable = 0;sometimes you need an unused variable. some uses in rust:
