get: Borrow an Element

Getting an element from a collection or container.

#![allow(unused)]
fn main() {
impl <T> Vec<T> {
    fn get(&self, index: usize) -> Option<&T> {...}
}

impl <T> OnceCell {
    fn get(&self) -> Option<&T> {...}
}
}
- Gets are trivial, they get a value!

Immutable by default, for the most part.

Should not panic. May return an option or result, depending on the framework.

  • Not for fields!

    For private fields you don’t want users to have direct, assign a method with a more descriptive name (or the same name as the field) is preferred.
