In this chapter, you will learn:

• How to write a single function definition, whose invocations can efficiently handle different data types

• How to use type inference to avoid the need to specify the types used by generic functions

• How to write a single struct, tuple-struct, or enum type, whose instances can contain efficiently different data types

• How to use two important standard generic enums, Option and Result, to represent optional data or fallible functions results

• How some standard functions ease the handling of Option and Result
