Enum async_mwmr::error::Error

pub enum Error<D: AsyncDatabase, P: AsyncPendingManager> {
    Transaction(TransactionError<P>),
    DB(D::Error),
}

Error type for the [TransactionDB].

Variants

Transaction(TransactionError<P>)

Returned if transaction related error occurs.

DB(D::Error)

Returned if DB related error occurs.

Implementations

impl<D: AsyncDatabase, P: AsyncPendingManager> Error<D, P>

pub fn database(err: D::Error) -> Self

Create a new error from the database error.

pub fn transaction(err: TransactionError<P>) -> Self

Create a new error from the transaction error.

Trait Implementations

impl<D: AsyncDatabase, P: AsyncPendingManager> Debug for Error<D, P>

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

Formats the value using the given formatter.

impl<D: AsyncDatabase, P: AsyncPendingManager> Display for Error<D, P>

where TransactionError<P>: Display,

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

Formats the value using the given formatter.

impl<D: AsyncDatabase, P: AsyncPendingManager> Error for Error<D, P>

where TransactionError<P>: Error, Self: Debug + Display,

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

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<D: AsyncDatabase, P: AsyncPendingManager> From<TransactionError<P>> for Error<D, P>

fn from(source: TransactionError<P>) -> Self

Converts to this type from the input type.
