Fundamental Data Structures

[zachwolfe]

Part 1:

• Vec
• String
• Slices

Part 2, after #45 and #46:

• Option
• Result
• Basic (traitless, sugarless) iterators, example:

numbers := Vec[usize].new()
// Initialize `numbers`...

// Loop through and print each element of `numbers`
iter := numbers.iterator()
while true {
    match iter.next() {
        .some(next) => print(next)
        .none => break
    }
}

• HashMap
• HashSet
