- The code is single threaded.
- I do not expect to run into any double borrow_mut() issues.
I'm doing some dynamic programming / memorization which requires building a cache of sorts. I'm 99% convinced, given conditions 1 & 2 above, that
RefCell<Vec<T>> is strictly superior to
Vec<RefCell<T>> (because we only pay the memory cost of one RefCell). However, this is my first time doing memorization in Rust, so if I'm wrong / unaware of reasons to use
Vec<RefCell<T>>, I'm interested in hearing them as well.
