Struct qt_core::q_library::LoadHint

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

This enum describes the possible hints that can be used to change the way libraries are handled when they are loaded. These values indicate how symbols are resolved when libraries are loaded, and are specified using the setLoadHints() function.

C++ enum: QLibrary::LoadHint.

C++ documentation:

This enum describes the possible hints that can be used to change the way libraries are handled when they are loaded. These values indicate how symbols are resolved when libraries are loaded, and are specified using the setLoadHints() function.

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

See also loadHints.

Implementations

impl LoadHint

pub fn to_int(&self) -> c_int

impl LoadHint

pub const ResolveAllSymbolsHint: LoadHint = _

Causes all symbols in a library to be resolved when it is loaded, not simply when resolve() is called. (C++ enum variant: ResolveAllSymbolsHint = 1)

pub const ExportExternalSymbolsHint: LoadHint = _

Exports unresolved and external symbols in the library so that they can be resolved in other dynamically-loaded libraries loaded later. (C++ enum variant: ExportExternalSymbolsHint = 2)

pub const LoadArchiveMemberHint: LoadHint = _

Allows the file name of the library to specify a particular object file within an archive file. If this hint is given, the filename of the library consists of a path, which is a reference to an archive file, followed by a reference to the archive member. (C++ enum variant: LoadArchiveMemberHint = 4)

pub const PreventUnloadHint: LoadHint = _

Prevents the library from being unloaded from the address space if close() is called. The library’s static variables are not reinitialized if open() is called at a later time. (C++ enum variant: PreventUnloadHint = 8)

pub const DeepBindHint: LoadHint = _

Instructs the linker to prefer definitions in the loaded library over exported definitions in the loading application when resolving external symbols in the loaded library. This option is only supported on Linux. (C++ enum variant: DeepBindHint = 16)

Trait Implementations

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

type Output = QFlags<LoadHint>

The resulting type after applying the | operator.

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

Performs the | operation.

impl Clone for LoadHint

fn clone(&self) -> LoadHint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LoadHint

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

Formats the value using the given formatter.

impl From<LoadHint> for QFlags<LoadHint>

fn from(value: LoadHint) -> Self

Converts to this type from the input type.

impl From<LoadHint> for c_int

fn from(value: LoadHint) -> Self

Converts to this type from the input type.

impl From<i32> for LoadHint

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for LoadHint

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