Struct TransactionInProgressException

#[non_exhaustive]
pub struct TransactionInProgressException {
    pub message: Option<String>,
    /* private fields */
}

The transaction with the given request token is already in progress.

Recommended Settings

This is a general recommendation for handling the TransactionInProgressException. These settings help ensure that the client retries will trigger completion of the ongoing TransactWriteItems request.

• Set clientExecutionTimeout to a value that allows at least one retry to be processed after 5 seconds have elapsed since the first attempt for the TransactWriteItems operation.

• Set socketTimeout to a value a little lower than the requestTimeout setting.

• requestTimeout should be set based on the time taken for the individual retries of a single HTTP request for your use case, but setting it to 1 second or higher should work well to reduce chances of retries and TransactionInProgressException errors.

• Use exponential backoff when retrying and tune backoff if needed.

Assuming default retry policy, example timeout settings based on the guidelines above are as follows:

Example timeline:

• 0-1000 first attempt

• 1000-1500 first sleep/delay (default retry policy uses 500 ms as base delay for 4xx errors)

• 1500-2500 second attempt

• 2500-3500 second sleep/delay (500 * 2, exponential backoff)

• 3500-4500 third attempt

• 4500-6500 third sleep/delay (500 * 2^2)

• 6500-7500 fourth attempt (this can trigger inline recovery since 5 seconds have elapsed since the first attempt reached TC)

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

Implementations

impl TransactionInProgressException

pub fn message(&self) -> Option<&str>

Returns the error message.

impl TransactionInProgressException

pub fn builder() -> TransactionInProgressExceptionBuilder

Creates a new builder-style object to manufacture TransactionInProgressException.

Trait Implementations

impl Clone for TransactionInProgressException

fn clone(&self) -> TransactionInProgressException

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TransactionInProgressException

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

Formats the value using the given formatter.

impl Display for TransactionInProgressException

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

Formats the value using the given formatter.

impl Error for TransactionInProgressException

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 PartialEq for TransactionInProgressException

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

impl ProvideErrorMetadata for TransactionInProgressException

fn meta(&self) -> &ErrorMetadata

Returns error metadata, which includes the error code, message, request ID, and potentially additional information.

fn code(&self) -> Option<&str>

Returns the error code if it’s available.

fn message(&self) -> Option<&str>

Returns the error message, if there is one.

impl RequestId for TransactionInProgressException

fn request_id(&self) -> Option<&str>

Returns the request ID, or None if the service could not be reached.
