This is really useful; I have been recently working on a huge c++ project and I had the exact same problem you mentioned with large vectors. The way I handled this problem was to wrap vector in a class which provides locking mechanism for expanding operations so while the vector is growing nobody can access it. I am excited to try Rust soon.
