AtomicRefCell for debug mode and UnsafeCell in release mode.
AtomicRefCell performs an atomic memory access at runtime to validate borrowing. While
this is an excellent way to validate code and ensure safety, it is an expensive
operation. This crate delegates to AtomicRefCell in debug mode and uses UnsafeCell to
emulate the same interface in release mode, minus the runtime overhead.
safeenables unconditional runtime checks, good for validating inreleasemode
- No try-borrows, as they are impossible to (properly) implement without overhead
borrowandborrow_mutareunsafe(despite being safe indebugmode)- No
PartialEq,Eq,PartialOrd,Ord, etc. due to the above
