Struct TransactionError 

pub struct TransactionError { /* private fields */ }

Transaction Error Type

Design principles:

1. Small size: Uses boxed errors to keep struct size minimal (~24 bytes)
2. Full context: Preserves error chain
3. Clone support: Can be cloned for logging/propagation

pub fn is_retryable(&self) -> bool

Returns true when this error indicates a transient failure that the client may retry by re-executing the entire transaction.

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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<Error> for TransactionError

fn from(e: Error) -> Self

Converts to this type from the input type.
