Finalize function -> size_t2024 Victor Ciura | @ciura_victor - Unleashing 🦀 separately accessible: 1. Init / construction of the hasher 2. Write overloads for primitive/std types (append to the hash) 3. Finalize function -> size_t This technique ensures that: we no longer need to the need to touch the data model and how each field recursively contributes to the overall digest (append/write). 🔶 The same technique can be used with almost every existing hashing algorithm, eg.
