Template Constraints
Explore how template constraints in D control which template instantiations are valid, preventing compile-time errors caused by incompatible types. Understand the use of logical conditions and is expressions in constraints to write more robust and flexible template code. This lesson helps you improve template safety and clarity in your advanced D programming projects.
We'll cover the following...
Incompatibility
The fact that templates can be instantiated with any argument yet not every argument is compatible with every template brings an inconvenience. If a template argument is not compatible with a particular template, the incompatibility is necessarily detected during the compilation of the template code for that argument. As a result, the compilation error points at a line inside the template implementation.
Let’s see this by using useSoundEmittingObject() with a type that ...
