90% "susahnya" Rust ada di 3 konsep ini

== Ownership ==
*Every value is 'owned' by a single variable, struct, vector, etc at a time
*Reassigning the value to another variable, passing it to a function, putting it into a vector, etc, '''MOVES''' the value. The old variable can't be used anymore

== Borrowing ==
*You can create many read-only references to a value that exist at the same time
*You can't move a value while a ref to the value exist
*You can make writable (mutable) reference to a value '''ONLY IF''' there are no read-only references currently in use. One mutable ref to a value can exist at a time
*You can't mutate a value through the owner when any ref (mutable or immutable) to the value exist
*Some types of values are '''COPIED''' instead of move (numbers, bools, chars, arrays/tuple with copyable elements)

== Lifetimes ==
*When a variable goes out of scope, the value owned by it is dropped (cleaned up in memory)
*Values can't be dropped if there are still active references to it
*References to a value can't outlive the value the refer to
