Struct InstanceCreateFlags 

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

Flags specifying additional properties of an instance.

Implementations

impl InstanceCreateFlags

pub const ENUMERATE_PORTABILITY: InstanceCreateFlags

Include portability subset devices when enumerating physical devices.

If you enable this flag, you must ensure that your program is prepared to handle the non-conformant aspects of these devices.

If this flag is not enabled, and there are no fully-conformant devices on the system, then Instance::new will return an IncompatibleDriver error.

The default value is false.

Notes

If this flag is enabled, and the khr_portability_enumeration extension is supported, it will be enabled automatically when creating the instance. If the extension is not supported, this flag will be ignored.

pub const fn empty() -> InstanceCreateFlags

Returns a InstanceCreateFlags with none of the flags set.

pub const fn none() -> InstanceCreateFlags

👎Deprecated since 0.31.0: use empty instead

Returns a InstanceCreateFlags with none of the flags set.

pub const fn count(self) -> u32

Returns the number of flags set in self.

pub const fn is_empty(self) -> bool

Returns whether no flags are set in self.

pub const fn intersects(self, other: InstanceCreateFlags) -> bool

Returns whether any flags are set in both self and other.

pub const fn contains(self, other: InstanceCreateFlags) -> bool

Returns whether all flags in other are set in self.

pub const fn union(self, other: InstanceCreateFlags) -> InstanceCreateFlags

Returns the union of self and other.

pub const fn intersection( self, other: InstanceCreateFlags, ) -> InstanceCreateFlags

Returns the intersection of self and other.

pub const fn difference(self, other: InstanceCreateFlags) -> InstanceCreateFlags

Returns self without the flags set in other.

pub const fn symmetric_difference( self, other: InstanceCreateFlags, ) -> InstanceCreateFlags

Returns the flags that are set in self or other, but not in both.

Trait Implementations

The resulting type after applying the | operator.

fn bitor(self, rhs: InstanceCreateFlags) -> InstanceCreateFlags

Performs the | operation.

impl BitOrAssign for InstanceCreateFlags

fn bitor_assign(&mut self, rhs: InstanceCreateFlags)

Performs the |= operation.

impl BitXor for InstanceCreateFlags

type Output = InstanceCreateFlags

The resulting type after applying the ^ operator.

fn bitxor(self, rhs: InstanceCreateFlags) -> InstanceCreateFlags

Performs the ^ operation.

fn clone(&self) -> InstanceCreateFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InstanceCreateFlags

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

Formats the value using the given formatter.

impl Default for InstanceCreateFlags

fn default() -> InstanceCreateFlags

Returns the “default value” for a type.

impl From<InstanceCreateFlags> for InstanceCreateFlags

fn from(val: InstanceCreateFlags) -> InstanceCreateFlags

Converts to this type from the input type.

impl From<InstanceCreateFlags> for InstanceCreateFlags

fn from(val: InstanceCreateFlags) -> InstanceCreateFlags

impl Hash for InstanceCreateFlags

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for InstanceCreateFlags

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