Struct qt_core::q_file_device::MemoryMapFlags

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

This enum describes special options that may be used by the map() function.

C++ enum: QFileDevice::MemoryMapFlags.

C++ documentation:

This enum describes special options that may be used by the map() function.

This enum was introduced or modified in Qt 4.4.

Implementations

impl MemoryMapFlags

pub fn to_int(&self) -> c_int

impl MemoryMapFlags

pub const NoOptions: MemoryMapFlags = _

No options. (C++ enum variant: NoOptions = 0)

pub const MapPrivateOption: MemoryMapFlags = _

The mapped memory will be private, so any modifications will not be visible to other processes and will not be written to disk. Any such modifications will be lost when the memory is unmapped. It is unspecified whether modifications made to the file made after the mapping is created will be visible through the mapped memory. This enum value was introduced in Qt 5.4. (C++ enum variant: MapPrivateOption = 1)

Trait Implementations

impl Clone for MemoryMapFlags

fn clone(&self) -> MemoryMapFlags

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryMapFlags

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

Formats the value using the given formatter.

impl From<MemoryMapFlags> for c_int

fn from(value: MemoryMapFlags) -> Self

Converts to this type from the input type.

impl From<i32> for MemoryMapFlags

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for MemoryMapFlags

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