Implementations

impl MemoryPropertyFlags

pub const DEVICE_LOCAL: MemoryPropertyFlags = _

This flag is set for device-local memory types. Device-local memory is situated “close” to the GPU cores and allows for fast access.

pub const HOST_VISIBLE: MemoryPropertyFlags = _

This flag is set for host-visible memory types. Host-visible memory can be mapped to the host memory range.

pub const HOST_COHERENT: MemoryPropertyFlags = _

This flag is set for host-coherent memory types. Host-coherent memory does not requires manual invalidation for modifications on GPU to become visible on host; nor flush for modification on host to become visible on GPU. Access synchronization is still required.

pub const HOST_CACHED: MemoryPropertyFlags = _

This flag is set for host-cached memory types. Host-cached memory uses cache in host memory for faster reads from host.

pub const LAZILY_ALLOCATED: MemoryPropertyFlags = _

This flag is set for lazily-allocated memory types. Lazily-allocated memory must be used (and only) for transient image attachments.

pub const PROTECTED: MemoryPropertyFlags = _

This flag is set for protected memory types. Protected memory can be used for writing by protected operations and can be read only by protected operations. Protected memory cannot be host-visible. Implementation must guarantee that there is no way for data to flow from protected to unprotected memory.

Convert from a bits value exactly.

pub fn from_name(name: &str) -> Option<MemoryPropertyFlags>

pub fn remove(&mut self, other: MemoryPropertyFlags)

The intersection of a source flags value with the complement of a target flags value (&!).

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

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won’t truncate other, but the ! operator will.

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

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> MemoryPropertyFlags

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl MemoryPropertyFlags

pub const fn iter(&self) -> Iter<MemoryPropertyFlags>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<MemoryPropertyFlags>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
