# Vectors
|
||
|
|
|
||
|
|
Vectors are one of the most-used Rust data structures. In other programming
|
||
|
|
languages, they'd simply be called Arrays, but since Rust operates on a
|
||
|
|
bit of a lower level, an array in Rust is stored on the stack (meaning it
|
||
|
|
can't grow or shrink, and the size needs to be known at compile time),
|
||
|
|
and a Vector is stored in the heap (where these restrictions do not apply).
|
||
|
|
|
||
|
|
Vectors are a bit of a later chapter in the book, but we think that they're
|
||
|
|
useful enough to talk about them a bit earlier. We shall be talking about
|
||
|
|
the other useful data structure, hash maps, later.
