Ownership

Contains some of the basic general concepts of ownership and how Rust solves memory management without a garbage collector.

Basics

Set of rules that govern how Rust manages memory.

Approaches to manage memory

1. Garbage collection, regular looks for no-longer used memory as the program runs
2. Memory management, program must explicitly allocate / free memory
3. Ownership, memory is managed through set of rules that compiler checks

Stack / Heap

Parts of memory available to use at runtime, but structured in different ways.

Stack

Stores values in order it gets them / removes them in the opposite order –> last in, first out.

Adding Data –> Pushing onto the stack

Removing Data –> Popping off the stack
