Fixed size container for buffer in CircularDeque #958
Description
Would it make sense to switch from Vector as the container for buffer of CircularDeque (and potentially other fixed size containers)? Since we have Memory{T} and FixedSizeArray they could eliminate a pointer jump. Or the performance gain is expected to be negligible?
The concerns I see are:
- compatibility with older julia versions and
Base._unsetindex!trickery required for proper garbage collection as mentioned in Deque leaks memory #884 and also discussed in MakeBase._unsetindex!(or a function like it) Public JuliaLang/julia#58943

We can always use a
or something like that
At least on the current version, this function is also overloaded for
Memory.This seems a fine change as far as the issues go
However, I am not sure if there is any performance or otherwise gain from doing this.
