Struct MemoryPropertyFlags

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

Bitmask specifying properties for a memory type

Implementations

impl MemoryPropertyFlags

pub const fn bits(&self) -> VkMemoryPropertyFlags

Returns bits in this flags

pub const fn has_any(self, other: Self) -> bool

Returns true if any of specified bits are contained in this flag.

pub const fn has_all(self, other: Self) -> bool

Returns true if all of specified bits are contained in this flag.

pub const fn merge(self, other: Self) -> Self

merge two flags (const alias of BitOr)

impl MemoryPropertyFlags

pub const EMPTY: Self

Empty set

pub const DEVICE_LOCAL: Self

Memory allocated with this type is the most efficient for device access

pub const HOST_VISIBLE: Self

Memory allocated with this type can be mapped for host access using vkMapMemory

pub const HOST_COHERENT: Self

The host cache management commands vkFlushMappedMemoryRanges and vkInvalidateMappedMemoryRanges are not needed to flush host writes to the device or make device writes visible to the host, respectively.

pub const HOST_CACHED: Self

Memory allocated with this type is cached on the host. Host memory accesses to uncached memory are slower than to cached memory, however uncached memory is always host coherent

pub const LAZILY_ALLOCATED: Self

The memory type only allows device access to the memory.

pub const PROTECTED: Self

Available on crate feature Allow1_1APIs only.

The memory type only allows device access to the memory, and allows protected queue operations to access the memory.

Trait Implementations

impl BitAnd for MemoryPropertyFlags

type Output = MemoryPropertyFlags

The resulting type after applying the & operator.

fn bitand(self, rhs: Self) -> Self

Performs the & operation.

impl BitAndAssign for MemoryPropertyFlags

fn bitand_assign(&mut self, rhs: Self)

Performs the &= operation.

impl BitOr for MemoryPropertyFlags

type Output = MemoryPropertyFlags

The resulting type after applying the | operator.

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

Performs the | operation.

impl BitOrAssign for MemoryPropertyFlags

fn bitor_assign(&mut self, rhs: Self)

Performs the |= operation.

impl Clone for MemoryPropertyFlags

fn clone(&self) -> MemoryPropertyFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryPropertyFlags

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

Formats the value using the given formatter.

impl From<MemoryPropertyFlags> for VkMemoryPropertyFlags

fn from(value: MemoryPropertyFlags) -> Self

Converts to this type from the input type.

impl Not for MemoryPropertyFlags

type Output = MemoryPropertyFlags

The resulting type after applying the ! operator.

fn not(self) -> Self

Performs the unary ! operation.

impl PartialEq for MemoryPropertyFlags

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