Enum TransactionError 

pub enum TransactionError<E> {
    Begin(E),
    Commit(E),
    Rollback(E),
    Operation(E),
}

Error type for transaction operations.

Wraps database errors and provides context about the transaction state.

Variants

Begin(E)

Failed to begin transaction.

Commit(E)

Failed to commit transaction.

Rollback(E)

Failed to rollback transaction.

Operation(E)

Operation within transaction failed.

Implementations

impl<E> TransactionError<E>

pub const fn is_begin(&self) -> bool

Check if this is a begin error.

pub const fn is_commit(&self) -> bool

Check if this is a commit error.

pub const fn is_rollback(&self) -> bool

Check if this is a rollback error.

pub const fn is_operation(&self) -> bool

Check if this is an operation error.

pub fn into_inner(self) -> E

Get the inner error.

Trait Implementations

impl<E> Debug for TransactionError<E>

where E: Debug,

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

Formats the value using the given formatter.

impl<E> Display for TransactionError<E>

where E: Display,

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

Formats the value using the given formatter.

impl<E> Error for TransactionError<E>

where E: Error + 'static,

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.
