Struct Permission

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

This enum is used by the permission() function to report the permissions and ownership of a file. The values may be OR-ed together to test multiple permissions and ownership values.

C++ enum: QFileDevice::Permission.

C++ documentation:

This enum is used by the permission() function to report the permissions and ownership of a file. The values may be OR-ed together to test multiple permissions and ownership values.

Warning: Because of differences in the platforms supported by Qt, the semantics of ReadUser, WriteUser and ExeUser are platform-dependent: On Unix, the rights of the owner of the file are returned and on Windows the rights of the current user are returned. This behavior might change in a future Qt version.

Note: On NTFS file systems, ownership and permissions checking is disabled by default for performance reasons. To enable it, include the following line:

extern Q_CORE_EXPORT int qt_ntfs_permission_lookup;

Permission checking is then turned on and off by incrementing and decrementing qt_ntfs_permission_lookup by 1.

qt_ntfs_permission_lookup++; // turn checking on
qt_ntfs_permission_lookup--; // turn it off again

The Permissions type is a typedef for QFlags<Permission>. It stores an OR combination of Permission values.

Implementations

impl Permission

pub fn to_int(&self) -> c_int

impl Permission

pub const ReadOwner: Permission

The file is readable by the owner of the file. (C++ enum variant: ReadOwner = 16384)

pub const WriteOwner: Permission

The file is writable by the owner of the file. (C++ enum variant: WriteOwner = 8192)

pub const ExeOwner: Permission

The file is executable by the owner of the file. (C++ enum variant: ExeOwner = 4096)

pub const ReadUser: Permission

The file is readable by the user. (C++ enum variant: ReadUser = 1024)

pub const WriteUser: Permission

The file is writable by the user. (C++ enum variant: WriteUser = 512)

pub const ExeUser: Permission

The file is executable by the user. (C++ enum variant: ExeUser = 256)

pub const ReadGroup: Permission

The file is readable by the group. (C++ enum variant: ReadGroup = 64)

pub const WriteGroup: Permission

The file is writable by the group. (C++ enum variant: WriteGroup = 32)

pub const ExeGroup: Permission

The file is executable by the group. (C++ enum variant: ExeGroup = 16)

pub const ReadOther: Permission

The file is readable by anyone. (C++ enum variant: ReadOther = 4)

pub const WriteOther: Permission

The file is writable by anyone. (C++ enum variant: WriteOther = 2)

pub const ExeOther: Permission

The file is executable by anyone. (C++ enum variant: ExeOther = 1)

Trait Implementations

impl<T: Into<QFlags<Permission>>> BitOr<T> for Permission

type Output = QFlags<Permission>

The resulting type after applying the | operator.

fn bitor(self, rhs: T) -> QFlags<Permission>

Performs the | operation.

impl Clone for Permission

fn clone(&self) -> Permission

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Permission

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

Formats the value using the given formatter.

impl From<Permission> for QFlags<Permission>

fn from(value: Permission) -> Self

Converts to this type from the input type.

impl From<Permission> for c_int

fn from(value: Permission) -> Self

Converts to this type from the input type.

impl From<i32> for Permission

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for Permission

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Copy for Permission

impl Eq for Permission
