Fields

path: PathBuf

key: Option<Zeroizing<String>>

SQLCipher passphrase-style key (base64-ish charset). See also DbOptions::raw_key.

raw_key: Option<Zeroizing<[u8; 32]>>

SQLCipher raw 256-bit key, applied as x'<hex>' (no KDF). Takes precedence over key.

profile: CacheProfile

durability: DurabilityProfile

foreign_keys: bool

integrity_check_on_open: bool

journal: JournalSelect

owner_only: bool

Narrow the database and its sidecars to owner-only (0600) on unix. Default on.

init: Option<ConnInit>

Implementations

impl DbOptions

pub fn open_writer_migrated( &self, migrations: &[Migration], options: &MigrateOptions, ) -> Result<(Connection, MigrationReport)>

Open the writer and bring the schema up to date (see migrate); the pre-migration backup is keyed like the database itself.

impl DbOptions

pub fn open_writer_with_key_candidates( &self, candidates: &[Zeroizing<String>], ) -> Result<(Connection, usize)>

Try each passphrase in order; the first that decrypts opens the writer.

pub fn open_writer_recovering( &self, policy: RecoveryPolicy, ) -> Result<OpenOutcome>

Open the writer; if the file is unreadable and the policy allows it, quarantine it and open a fresh database at the same path.

impl DbOptions

pub fn new(path: impl Into<PathBuf>) -> Self

pub fn with_passphrase(self, key: impl Into<String>) -> Self

pub fn with_raw_key(self, key: [u8; 32]) -> Self

pub fn is_keyed(&self) -> bool

pub fn open_writer(&self) -> Result<Connection>

pub fn open_reader(&self) -> Result<Connection>

pub fn open_read_pool(&self, cap: usize) -> Result<ReadPool>

Trait Implementations

impl Clone for DbOptions

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
