1 # Vectors 2 3 Vectors are one of the most-used Rust data structures. In other programming 4 languages, they'd simply be called Arrays, but since Rust operates on a 5 bit of a lower level, an array in Rust is stored on the stack (meaning it 6 can't grow or shrink, and the size needs to be known at compile time), 7 and a Vector is stored in the heap (where these restrictions do not apply). 8 9 Vectors are a bit of a later chapter in the book, but we think that they're 10 useful enough to talk about them a bit earlier. We shall be talking about 11 the other useful data structure, hash maps, later. 12 13 ## Further information 14 15 - [Storing Lists of Values with Vectors](https://doc.rust-lang.org/book/ch08-01-vectors.html) 16 - [`iter_mut`](https://doc.rust-lang.org/std/primitive.slice.html#method.iter_mut) 17 - [`map`](https://doc.rust-lang.org/std/iter/trait.Iterator.html#method.map)
