The nice thing about this pattern wrt mutability is that the mutability is scoped very tightly to the statement, since it's not often that you'd need a builder to live longer than a single statement or at the very most the lifetime of the builder. Although I've had to allow a builder to live longer than a single statement for things in the past, nothing is coming to mind at the moment. Because Rust enforces single ownership of mutable resources, it's not all that bad. |
