Enum TryLockError

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

🔬This is a nightly-only experimental API. (file_lock #130994)

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)

🔬This is a nightly-only experimental API. (file_lock #130994)

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

🔬This is a nightly-only experimental API. (file_lock #130994)

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