Rust uses ownership semantics for memory management.

General

Stack

The stack is

• a LIFO
• push=add, pop=remove (from the top)
• only supports fixed-size datatypes
• fast

Heap

• access provided through pointers (a fixed-size, usable on stack)
• slower

Ownership

• Objects have a single owner at once
• When owner goes out of scope, value is dropped (with drop())

See example of ownership in action.
