Enum LockError 

#[non_exhaustive]
pub enum LockError {
    Held {
        path: PathBuf,
    },
    Io {
        path: PathBuf,
        source: Error,
    },
}

Failure to create or commit a lock file.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Held

Another process holds the lock (or the lock path already exists).

Fields

path: PathBuf

Path to the lock file that could not be created exclusively.

Io

Underlying I/O failure while creating, writing, syncing, or renaming.

Fields

path: PathBuf

Lock file path associated with the failure.

source: Error

Underlying OS error.

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, __formatter: &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<LockError> for Error

fn from(err: LockError) -> Self

LockError::Held becomes Error::LockHeld with the recorded LockHolder, and I/O failures become Error::Io.
