This is partially why allocation is left to the caller (concurrent data structures are often intrusive), have single consumers (made lock free using separate synchronization) or only have lockless guarantees not obstruction freedom. I think the obnoxious part in Rust is doing intrusive and shared mutability parts of data structures. Having to go between NonNulls, Options, Pin, and Cell/UnsafeCell is not a pleasant experience. |
