Updating vector elements in Rust in Rust

The entries of vectors are mutable and can be changed freely, using indices and the bracket notation, just like we do with static arrays:

let mut names = vec!["Andy", "Mary", "Cody"];

names[0] = "Mircea";
names[2] = "Mike";

// names is now ["Mircea", "Mary", "Cody"]
