Why `freq` is no longer valid
I’m struggling with the borrow checker and hope anyone can give me a clue.
How to store references that don’t outlive its container
I want to store references that don’t outlive its container (internally, those references are stored as pointers). Those references are not necessarily set when the container is constructed.
Returning a reference from a HashMap or Vec causes a borrow to last beyond the scope it’s in?
I’ve got a persistent compile error where Rust complains that I have an immutable borrow while I’m trying to mutably borrow, but the immutable borrow is from another scope, and I’m not bringing anything across from it.
Indexing from `HashMap` with `&str`
What is the proper way to index into a HashMap<&String, V> with a &str? Rust reports that &String is not Borrow<str>, which is required for indexing. (This seems a bit silly to me; if T: Borrow<U> then surely &T: Borrow<U> should also hold?)
Double mutable borrow error in a loop happens even with NLL on
Suppose I have several structures like in the following example, and in the next() method I need to pull the next event using a user-provided buffer, but if this event is a comment, and ignore comments flag is set to true, I need to pull the next event again:
