In the Rust programming language, we usually cannot directly modify the value of an immutable reference, and we cannot convert an immutable reference directly to a mutable one (which would be an undefined behavior). However, RefCell provides a mechanism that allows us to modify the internal value while maintaining an immutable reference.\n\nRefCell acts as a layer of protection for the internal value, enabling us  to borrow and modify Accounts securely. By using RefCell, we can ensure that the Account values remain safe during the borrowing and modification process."}]}],"pr":"ae160fd5aef097e537f8ca478ebd0f89ac1424ee3919fae673266b12301c5b01"}
