Implementations

impl SharedMemoryError

pub fn to_int(&self) -> c_int

impl SharedMemoryError

pub const NoError: SharedMemoryError = _

No error occurred. (C++ enum variant: NoError = 0)

pub const PermissionDenied: SharedMemoryError = _

The operation failed because the caller didn’t have the required permissions. (C++ enum variant: PermissionDenied = 1)

pub const InvalidSize: SharedMemoryError = _

A create operation failed because the requested size was invalid. (C++ enum variant: InvalidSize = 2)

pub const KeyError: SharedMemoryError = _

The operation failed because of an invalid key. (C++ enum variant: KeyError = 3)

pub const AlreadyExists: SharedMemoryError = _

A create() operation failed because a shared memory segment with the specified key already existed. (C++ enum variant: AlreadyExists = 4)

pub const NotFound: SharedMemoryError = _

An attach() failed because a shared memory segment with the specified key could not be found. (C++ enum variant: NotFound = 5)

pub const LockError: SharedMemoryError = _

The attempt to lock() the shared memory segment failed because create() or attach() failed and returned false, or because a system error occurred in QSystemSemaphore::acquire(). (C++ enum variant: LockError = 6)

pub const OutOfResources: SharedMemoryError = _

A create() operation failed because there was not enough memory available to fill the request. (C++ enum variant: OutOfResources = 7)

pub const UnknownError: SharedMemoryError = _

Something else happened and it was bad. (C++ enum variant: UnknownError = 8)

Trait Implementations

impl Clone for SharedMemoryError

fn clone(&self) -> SharedMemoryError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SharedMemoryError

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

Formats the value using the given formatter.

impl From<SharedMemoryError> for c_int

fn from(value: SharedMemoryError) -> Self

Converts to this type from the input type.

impl From<i32> for SharedMemoryError

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for SharedMemoryError

fn eq(&self, other: &SharedMemoryError) -> 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.
