Enum DbErrorKind 

#[non_exhaustive]
pub enum DbErrorKind {
    StaleVersion,
    NotFound,
    Other,
}

Available on crate features model-mysql or model-postgres or model-sqlite only.

What a DbError is about, for errors a caller handles differently from the rest (18.30.0).

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.

StaleVersion

save of a #[version]ed model whose version no longer matches the row’s: someone saved it since this copy was read. Reload and retry, or tell the user.

NotFound

The row to update or restore doesn’t exist.

Other

Anything else: SQL errors, connection errors, conversions.
