Episode notes
Generics Improve Safety & Performance
- Generics allow passing types to functions and methods, replacing unsafe dynamic type assertions and improving safety and performance.
- This avoids runtime panics and allocations when wrapping values in interfaces unnecessarily.
Go Escapes C++ Generics Pitfalls
- Go has avoided the complexity and overuse pitfalls of C++ templates despite generics being new in 1.18.
- The community has not abused generics yet, but it is early to predict long-term patterns.
Generics Enable Devirtualized Performance
- Go generics can produce faster code by compiling down to machine instructions, avoiding dynamic dispatch.
- This yields significant speed-ups especially for common types like ints compared to interface-based methods.
