Expand description

Configuration for a database.

Fields§

§allow_create: bool

Allow database creation if it doesn’t exist.

§sorted_duplicates: bool

Enable sorted duplicates.

§key_prefixing: bool

Enable key prefixing compression.

§temporary: bool

Database is temporary (not persisted).

§transactional: bool

Database operations are transactional.

§read_only: bool

Database is read-only.

§node_max_entries: i32

Maximum entries per node.

§deferred_write: bool

Deferred write: skip WAL logging; flush only at eviction/checkpoint.

§btree_comparator: Option<ConfigComparator>

User-supplied B-tree key comparator (DBI-14).

JE DatabaseImpl.btreeComparator. None = unsigned-byte order.

§duplicate_comparator: Option<ConfigComparator>

User-supplied duplicate-data comparator (DBI-14).

JE DatabaseImpl.duplicateComparator.

§override_btree_comparator: bool

JE DatabaseConfig.overrideBtreeComparator: replace a persisted comparator instead of rejecting a mismatch.

§override_duplicate_comparator: bool

JE DatabaseConfig.overrideDuplicateComparator.

§triggers: Vec<Arc<dyn Trigger>>

User-supplied database / transaction triggers, fired in registration order (DB-TRIG).

JE DatabaseConfig.setTriggers / getTriggers (a List<Trigger>). Runtime-registered only: not persisted, not replicated — see crate::trigger.

Implementations§

Source§

impl DatabaseConfig

Source

pub fn new() -> Self

Creates a new DatabaseConfig with default values.

Source

pub fn set_allow_create(&mut self, allow_create: bool) -> &mut Self

Sets the allow_create flag.

Source

pub fn set_sorted_duplicates(&mut self, sorted_duplicates: bool) -> &mut Self

Sets the sorted_duplicates flag.

Source

pub fn set_key_prefixing(&mut self, key_prefixing: bool) -> &mut Self

Sets the key_prefixing flag.

Source

pub fn set_temporary(&mut self, temporary: bool) -> &mut Self

Sets the temporary flag.

Source

pub fn set_transactional(&mut self, transactional: bool) -> &mut Self

Sets the transactional flag.

Source

pub fn set_read_only(&mut self, read_only: bool) -> &mut Self

Sets the read_only flag.

Source

pub fn set_node_max_entries(&mut self, max: i32) -> &mut Self

Sets the maximum entries per node.

Source

pub fn add_trigger(&mut self, trigger: Arc<dyn Trigger>) -> &mut Self

Appends a trigger to the registration list (DB-TRIG).

Triggers fire in the order they are added. JE DatabaseConfig.setTriggers (Noxu allows incremental registration).
