Converting a Vec<Item> to Vec<Option<Item>> in Rust
// We need to use Vec::into_iter() instead of Vec::iter() to create a consuming
// iterator that moves each value out of the vector.
fn main() {
let v = vec![1, 2, 3];
let v: Vec<Option<i32>> = v.into_iter().map(Some).collect();

Created April 16, 2017 15:59
A Rust function that accepts both String or &str and creates a copy of it
// Item::new() accepts both &str and String. When called, it creates a copy of
// the parameter and uses it to initialize the returned item.
//
// The trick is in the use of the Into trait:
// https://doc.rust-lang.org/std/convert/trait.Into.html
