Struct qt_core::q_lock_file::LockError

pub struct LockError(/* private fields */);

This enum describes the result of the last call to lock() or tryLock().

C++ enum: QLockFile::LockError.

C++ documentation:

This enum describes the result of the last call to lock() or tryLock().

Implementations

impl LockError

pub fn to_int(&self) -> c_int

impl LockError

pub const NoError: LockError = _

The lock was acquired successfully. (C++ enum variant: NoError = 0)

pub const LockFailedError: LockError = _

The lock could not be acquired because another process holds it. (C++ enum variant: LockFailedError = 1)

pub const PermissionError: LockError = _

The lock file could not be created, for lack of permissions in the parent directory. (C++ enum variant: PermissionError = 2)

pub const UnknownError: LockError = _

Another error happened, for instance a full partition prevented writing out the lock file. (C++ enum variant: UnknownError = 3)

Trait Implementations

impl Clone for LockError

fn clone(&self) -> LockError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LockError

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

Formats the value using the given formatter.

impl From<LockError> for c_int

fn from(value: LockError) -> Self

Converts to this type from the input type.

impl From<i32> for LockError

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for LockError

fn eq(&self, other: &LockError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
