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.
