Struct FileHandleFlag

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

This enum is used when opening a file to specify additional options which only apply to files and not to a generic QIODevice.

C++ enum: QFileDevice::FileHandleFlag.

C++ documentation:

This enum is used when opening a file to specify additional options which only apply to files and not to a generic QIODevice.

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

Implementations

impl FileHandleFlag

pub fn to_int(&self) -> c_int

impl FileHandleFlag

pub const AutoCloseHandle: FileHandleFlag

The file handle passed into open() should be closed by close(), the default behavior is that close just flushes the file and the application is responsible for closing the file handle. When opening a file by name, this flag is ignored as Qt always owns the file handle and must close it. (C++ enum variant: AutoCloseHandle = 1)

pub const DontCloseHandle: FileHandleFlag

If not explicitly closed, the underlying file handle is left open when the QFile object is destroyed. (C++ enum variant: DontCloseHandle = 0)

Trait Implementations

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

type Output = QFlags<FileHandleFlag>

The resulting type after applying the | operator.

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

Performs the | operation.

impl Clone for FileHandleFlag

fn clone(&self) -> FileHandleFlag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FileHandleFlag

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

Formats the value using the given formatter.

impl From<FileHandleFlag> for QFlags<FileHandleFlag>

fn from(value: FileHandleFlag) -> Self

Converts to this type from the input type.

impl From<FileHandleFlag> for c_int

fn from(value: FileHandleFlag) -> Self

Converts to this type from the input type.

impl From<i32> for FileHandleFlag

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for FileHandleFlag

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