Stage 9.4: Dereferencing Revisited

The process of accessing / manipulating data that is being referred to by a reference (i.e. &i32) is called dereferencing.

References are used to access/manipulate data in two ways:

• Access to the referred data during assignment of variables.
• Access to fields or methods of the referred data.

Rust has some powerful operators that allow us to do this.
