Enum RetryDecision

#[non_exhaustive]
pub enum RetryDecision {
    Fdb(FdbError),
    Retry,
    Fatal,
}

What the retry loop of crate::Database::run does with a closure error.

Produced by RetryableError::retry_decision. In every case the C API remains the single retry governor: backoff, max retry delay and TransactionOption::RetryLimit are applied by fdb_transaction_on_error, never by a Rust-side budget.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Fdb(FdbError)

The error is, or wraps, this FdbError: hand it to on_error and let the C API judge retryability.

Retry

App-level retry request with no native error underneath (lock contention, optimistic-concurrency conditions). Routed through on_error with code 1020 (not_committed, retryable by definition), so backoff and retry limits apply uniformly.

Fatal

Not retryable: the loop returns the original error to the caller as-is.
