Struct RwDatabaseLock 

pub struct RwDatabaseLock { /* private fields */ }

Reader-Writer database lock for concurrent read access

Implements a shared-exclusive lock protocol:

• Multiple concurrent readers allowed
• Single exclusive writer
• Writer intent prevents reader starvation

Implementations

impl RwDatabaseLock

pub fn acquire_shared<P: AsRef<Path>>(db_path: P) -> Result<Self, LockError>

Acquire a shared (read-only) lock

Multiple processes can hold shared locks simultaneously. Blocks if a writer is active or waiting.

pub fn acquire_exclusive<P: AsRef<Path>>(db_path: P) -> Result<Self, LockError>

Acquire an exclusive (read-write) lock

Only one process can hold an exclusive lock. Blocks if any readers or another writer is active.

pub fn acquire_with_mode<P: AsRef<Path>>( db_path: P, mode: ConnectionMode, config: &LockConfig, ) -> Result<Self, LockError>

Acquire lock with specified mode and configuration

pub fn mode(&self) -> ConnectionMode

Get connection mode

pub fn is_readonly(&self) -> bool

Check if this is a read-only connection

Trait Implementations

impl Drop for RwDatabaseLock

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

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

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
