Struct freya::prelude::BorrowMutError

pub struct BorrowMutError {
    pub attempted_at: &'static Location<'static>,
    pub already_borrowed_at: Vec<&'static Location<'static>, Global>,
}

An error returned by [RefCell::try_borrow_mut].

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

attempted_at: &'static Location<'static>

Debug-only location of attempted borrow

already_borrowed_at: Vec<&'static Location<'static>, Global>

Debug-only locations of all current borrows
