#[non_exhaustive]pub enum DataErrorKind {

}Expand description
Failure classes. #[non_exhaustive]: match with a _ arm.
Variants (Non-exhaustive)§
This enum is marked as 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.
Config
Misconfiguration (missing driver feature, bad URL): permanent until a human intervenes.
Connection
Connection/pool failure: retryable — another replica or a later attempt may succeed.
Query
The statement itself failed (syntax, constraint, type): permanent.
Timeout
The operation timed out: retryable.
Conflict
Optimistic/duplicate conflict (unique violation, version clash):
permanent for this payload, but semantically distinct from Query
so idempotent upsert paths can branch on it.
Other
Unclassified (driver returned something we don’t recognise).
