| //! _🎵 Immutability never bothered me anyway 🎶_ |
| //! |
| //! This crate provides various "Frozen" collections. |
| //! |
| //! These are append-only collections where references to entries can be held |
| //! on to even across insertions. This is safe because these collections only |
| //! support storing data that's present behind some indirection -- i.e. `String`, |
| //! `Vec<T>`, `Box<T>`, etc, and they only yield references to the data behind the |
| //! allocation (`&str`, `&[T]`, and `&T` respectively) |
| //! |
| //! The typical use case is having a global cache of strings or other data which the rest of the program borrows from. |
