Struct DatabaseManager

Source

pub struct DatabaseManager { /* private fields */ }

Expand description

The process-local shared-core registry (spec §10.1, S1A-002).

Implementations§

Source §

impl DatabaseManager

Source

pub fn global() -> &'static DatabaseManager

The process-global registry (spec §10.1, S1A-002).

Source

pub fn open_shared( self: &'static DatabaseManager, root: impl AsRef<Path>, identity: OpenIdentity, ) -> Result<DatabaseHandle>

Attach to the one shared core for root, initializing it on first use (spec §10.1, S1A-002).

Concurrent attaches initialize exactly once: the first caller runs the full open path (recovery, WAL opening, open-generation advancement, table mounting) while the rest wait, then every caller receives a handle over the same core. Fails with DatabaseLocked while an exclusive Database owner holds the root, and vice versa.

Source

pub fn registered_entries(&self) -> usize

Number of registry entries (all states). Diagnostics and tests.
