Enum StmError

pub enum StmError {
    Failure,
    Retry,
}

Error of a single step of a transaction.

Variants

Failure

The call failed, because a variable, the computation depends on, has changed.

Retry

retry was called.

It may block until at least one read variable has changed.

Trait Implementations

impl Clone for StmError

fn clone(&self) -> StmError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StmError

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

Formats the value using the given formatter.

impl Display for StmError

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

Formats the value using the given formatter.

impl Error for StmError

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<E> From<StmError> for TransactionError<E>

fn from(source: StmError) -> Self

Converts to this type from the input type.

impl PartialEq for StmError

fn eq(&self, other: &StmError) -> 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.
