The standard error type for rullst-orm, shielding users from internal dependency errors.

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.

NotInitialized

The global ORM state has not been initialized yet.

AlreadyInitialized

The global ORM state was already initialized by an earlier call.

RecordNotFound

A record was not found in the database.

DatabaseError(String)

A general database or query error.

#[non_exhaustive]

UniqueViolation

A unique or primary-key constraint rejected the statement, for example a second user with the same email. Match it as UniqueViolation { .. }: later versions may add fields. Added in v13.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

constraint: Option<String>

The violated constraint or index, when the database names it: PostgreSQL does, SQLite and MySQL/MariaDB do not.

#[non_exhaustive]

ForeignKeyViolation

A foreign-key constraint rejected the statement: the referenced row does not exist, or a row still references the one being deleted. Match it as ForeignKeyViolation { .. }. Added in v13.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

constraint: Option<String>

The violated constraint, when the database names it: PostgreSQL does, SQLite and MySQL/MariaDB do not.

#[non_exhaustive]

UnsupportedSchemaChange

The connected database cannot make this schema change, for example adding a foreign key to an existing SQLite table. Schema::table returns it before running any statement. Match it as UnsupportedSchemaChange { .. }. Added in v13.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

driver: String

The SQL dialect: sqlite, postgres or mysql.

change: String

The change that cannot be made, and the usual alternative.

SerializationError(String)

A serialization or deserialization error (e.g., JSON).

CacheError(String)

A cache or event-related error.

PostCommit(String)

A database commit succeeded, but one or more post-commit effects failed.

Validation(String)

A validation error, such as invalid SQL identifiers.

Internal(String)

Other internal errors.

Trait Implementations

impl Clone for RullstError

fn clone(&self) -> Self
