Database is locked by another process

Fields

holder_pid: Option<u32>

PID of the process holding the lock (if known)

lock_path: PathBuf

Path to the lock file

Timeout

Lock acquisition timed out

Fields

elapsed: Duration

How long we waited

timeout: Duration

The configured timeout

StaleLock

Trait Implementations

impl Debug for LockError

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

Formats the value using the given formatter.

impl Display for LockError

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

Formats the value using the given formatter.

impl Error for LockError

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.

impl From<Error> for LockError

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<LockError> for SochDBError

fn from(e: LockError) -> Self

Converts to this type from the input type.
