Enum TransactionError 

pub enum TransactionError {
    AlreadyClosed,
    NoGraphGuard,
    NoStagedGraph,
    CursorActiveCommit,
    CursorActiveStatement,
    ReadOnlyMutation,
    StreamingRequiresReadWrite,
    ReadOnlyCommit,
    Poisoned,
}

Transaction-lifecycle invariant violations.

All variants used to be raised as anyhow!("...") strings. Surfacing them as a typed enum lets crate::LoraError route them onto stable LoraErrorCodes without phrase-matching the Display text.

Trait Implementations

impl Clone for TransactionError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransactionError

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

Formats the value using the given formatter.

impl Display for TransactionError

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

Formats the value using the given formatter.

impl Eq for TransactionError

impl Error for TransactionError

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<TransactionError> for LoraError

fn from(e: TransactionError) -> Self

Converts to this type from the input type.

impl PartialEq for TransactionError

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

Equality operator ==.

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

Inequality operator !=.
