Enum BorrowError

pub enum BorrowError {
    Dropped(ValueDroppedError),
    AlreadyBorrowedMut(AlreadyBorrowedMutError),
}

An error that can occur when trying to borrow a value.

Variants

Dropped(ValueDroppedError)

The value was dropped.

AlreadyBorrowedMut(AlreadyBorrowedMutError)

The value was already borrowed mutably.

Trait Implementations

impl Clone for BorrowError

fn clone(&self) -> BorrowError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BorrowError

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

Formats the value using the given formatter.

impl Display for BorrowError

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

Formats the value using the given formatter.

impl Error for BorrowError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<BorrowError> for BorrowMutError

fn from(error: BorrowError) -> BorrowMutError

Converts to this type from the input type.

impl PartialEq for BorrowError

fn eq(&self, other: &BorrowError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
