There is no connection. Rust has ARC which performs worse than the tracing GC.
Not everything has to be ARC though and arenas are strictly better than GCs lacking synchronization issues for allocation and not needing any scanning for deallocation.
Than Go's GC? I think that is fairly unlikely in most cases.
