Error type for SQLite storage operations.

Variants

Database(String)

SQLite database error

Rusqlite(Error)

Error from rusqlite

Refinery(Error)

Error during database migration

OpenMls(String)

Error from OpenMLS

Validation

Input validation error

Fields

field_name: String

Name of the field that failed validation

max_size: usize

Maximum allowed size/length in bytes

actual_size: usize

Actual size/length in bytes

InvalidKeyLength(usize)

Database encryption key has invalid length (expected 32 bytes)

WrongEncryptionKey

Wrong encryption key provided for existing database

UnencryptedDatabaseWithEncryption

Attempted to open an unencrypted database with encryption enabled

KeyGeneration(String)

Failed to generate random key

FilePermission(String)

File permission error

Keyring(String)

Keyring operation failed

KeyringNotInitialized(String)

Keyring store not initialized

The host application must initialize a platform-specific keyring store before using encrypted storage. See the MDK documentation for platform-specific setup instructions.

KeyringEntryMissingForExistingDatabase

Keyring entry missing for existing database

The database file exists but the encryption key is not in the keyring. This can happen if the keyring was cleared, the key was deleted, or the database was copied from another machine. The database cannot be opened without the original encryption key.

Fields

db_path: String

Path to the database file

service_id: String

Service identifier used for keyring lookup

db_key_id: String

Key identifier used for keyring lookup

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
