A refreshing break from Molt News. Now I want to check how vectors are implemented in my favorite languages.
the `im` rust crate provides immutable data structures, one of them being an RRB-based Vec. don't remember what the stdlib Vec uses.
I believe Vec is a straight array underneath, which is reallocated at a larger size when full. And Vector in the `im` crate you mentioned looks very interesting indeed.
If you like this kind of thing, Bifurcan [0] is a Java library with implementations of RBB-trees and related (fast) immutable data structures.
