// This object needs to share references to multiple members of its Rust | ||||
// inner struct, namely `copy_map`, `dirs` and `all_dirs`. | ||||
// Right now `CopyMap` is done, but it needs to have an explicit reference | ||||
// to `RustDirstateMap` which itself needs to have an encapsulation for | ||||
// every method in `CopyMap` (copymapcopy, etc.). | ||||
// This is ugly and hard to maintain. | ||||
// The same logic applies to `dirs` and `all_dirs`, however the `Dirs` | ||||
// `py_class!` is already implemented and does not mention | ||||
// `RustDirstateMap`, rightfully so. | ||||
// All attributes also have to have a separate refcount data attribute for | ||||
// leaks, with all methods that go along for reference sharing. | ||||
