#[non_exhaustive]pub enum ErrorKind {
UniqueViolation,
ForeignKeyViolation,
NotNullViolation,
CheckViolation,
Other,
}
Expand description
The error kind.
This enum is to be used to identify frequent errors that can be handled by the program. Although it currently only supports constraint violations, the type may grow in the future.
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.
UniqueViolation
Unique/primary key constraint violation.
ForeignKeyViolation
Foreign key constraint violation.
NotNullViolation
Not-null constraint violation.
CheckViolation
Check constraint violation.
Other
An unmapped error.
