Very simple Rust library useful when you want stronger type guarantees than Slab's usize keys. Generates TSlab(Slab<T>) that accepts TKey instead of usize. TVacantEntry(VacantEntry<T>) is also generated along the same lines. This should be a drop-in replacement for Slab<T>, provided all the keys are changed from usize to TKey.
```rust use wrapped_slab::WrappedSlab;
struct TestUnitStruct(String);
fn main() { let mut slab = TestUnitStructSlab::default(); let key: TestUnitStructKey = slab.insert(TestUnitStruct("testing".into())); let val: Option<&TestUnitStruct> = slab.get(key); let nextentry: TestUnitStructVacantEntry = slab.vacantentry(); let nextkey: TestUnitStructKey = nextentry.key(); let nextentryref: &mut TestUnitStruct = nextentry.insert(TestUnitStruct(format!("{nextkey:?}")));
// See wrapped_slab/tests/ for more examples
} ```
