Vec in std::vec - Rust

A contiguous growable array type, written as Vec<T>, short for ‘vector’. §Examples let mut vec = Vec::new(); vec.push(1); vec.push(2); assert_eq!(vec.len(), 2); assert_eq!(vec[0], 1); assert_eq!(vec.pop(), Some(2)); assert_eq!(vec.len(), 1); vec[0] = 7; assert_eq!(vec[0], 7); vec.extend([1, 2, 3]); for x in &vec { println!("{x}"); } assert_eq!(vec, [7, 1, 2, 3]);Run
