Enum BorrowMutError

pub enum BorrowMutError {
    Borrowed,
    EmptySlot,
}

The error returned when a mutable borrow fails.

Variants

Borrowed

Couldn’t borrow because the elastic was already borrowed somewhere.

EmptySlot

Couldn’t borrow because the elastic either hadn’t been loaned to, or any outstanding loaned values were already repossessed by destroying their ElasticGuard.

Trait Implementations

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BorrowMutError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for BorrowMutError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting
