- 1 Intro
- 2 Safe, performant, reusable code
- 3 (Mostly) typeless programming
- 4 Machine-typed programming
- 5 Type-rich programming
- 6 The miracle of compilation Runtime
- 7 Physical types
- 8 Whole Value pattern
- 9 Templates to the rescue
- 10 Adding checking of values
- 11 Reuse through client libraries
- 12 Physical quantities and dimensions
- 13 Tailoring operations - library code
- 14 Tailoring operations - client code
- 15 Templates and policies
- 16 Implementing policies • Let's use a policy on overflow
- 17 Constructor validation logic • Let's use a policy to enforce that quantities are non-negative
- 18 Effect of constructor validation logic . So, what about the generated code?
- 19 Starting to define a domain type . We have now restricted both the operations and the range of allowed values
- 20 Domain types vs primitives • Business rules still exist when using primitives: they are just distributed
- 21 Compile-time range calculation
- 22 Scaling and errors • As systems get larger the number of possible combinations of types (and therefore incompatibilities) grows even faster
- 23 Templates and "concepts lite"
- 24 Concepts code - first attempt
