Enum TryLockError 

pub enum TryLockError {
    Error(Error),
    WouldBlock,
}

An enumeration of possible errors which can occur while trying to acquire a lock from the try_lock method and try_lock_shared method on a File.

Variants

Error(Error)

The lock could not be acquired due to an I/O error on the file. The standard library will not return an ErrorKind::WouldBlock error inside TryLockError::Error

WouldBlock

The lock could not be acquired at this time because it is held by another handle/process.

Trait Implementations

impl Debug for TryLockError

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

Formats the value using the given formatter.

impl Display for TryLockError

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

Formats the value using the given formatter.

impl Error for TryLockError

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<TryLockError> for Error

fn from(err: TryLockError) -> Error

Converts to this type from the input type.
