digitalmars.D.learn - How to hash any type to an integer?
- Gary Willoughby (6/6) May 29 2016 I'm currently implementing a hash map as an exercise and wondered
- Seb (3/10) May 29 2016 How about hashOf?
- Gary Willoughby (2/13) May 30 2016 Awesome, thanks. Can't believe I missed that.
I'm currently implementing a hash map as an exercise and wondered if there is a built-in function I could use to hash keys effectively? What I'm looking for is a function that hashes any variable (of any type) to an integer. I've been looking at the `getHash` function of the `TypeInfo` class but that only seems to return the passed pointer. Any ideas?
