fix(option2): Rename uninformative variables
Renaming uninformative names like `optional_value`, `value`, `optional_values_vec` and `value` helps users distinguish between the two parts of the task.
// I AM NOT DONE
fn main() {
- let optional_value = Some(String::from("rustlings"));
+ let optional_word = Some(String::from("rustlings"));
// TODO: Make this an if let statement whose value is "Some" type
- value = optional_value {
- println!("the value of optional value is: {}", value);
+ word = optional_word {
+ println!("The word is: {}", word);
} else {
- println!("The optional value doesn't contain anything!");
+ println!("The optional word doesn't contain anything");
}
- let mut optional_values_vec: Vec<Option<i8>> = Vec::new();
+ let mut optional_integers_vec: Vec<Option<i8>> = Vec::new();
for x in 1..10 {
- optional_values_vec.push(Some(x));
+ optional_integers_vec.push(Some(x));
}
// TODO: make this a while let statement - remember that vector.pop also adds another layer of Option<T>
// You can stack `Option<T>`'s into while let and if let
- value = optional_values_vec.pop() {
- println!("current value: {}", value);
+ integer = optional_integers_vec.pop() {
+ println!("current value: {}", integer);
}
}
