Memory properties type.

Implementations§

source§

impl MemoryPropertyFlags

source

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.

source

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.

source

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.

source

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.

source

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.

source

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.

impl MemoryPropertyFlags

source

pub const fn empty() -> MemoryPropertyFlags

Get a flags value with all bits unset.

source

pub const fn all() -> MemoryPropertyFlags

Get a flags value with all known bits set.

source

pub const fn bits(&self) -> u8

Get the underlying bits value.

The returned value is exactly the bits set in this flags value.

source

pub const fn from_bits(bits: u8) -> Option<MemoryPropertyFlags>

Convert from a bits value.

This method will return None if any unknown bits are set.

source

pub const fn from_bits_truncate(bits: u8) -> MemoryPropertyFlags

Convert from a bits value, unsetting any unknown bits.

source

pub const fn from_bits_retain(bits: u8) -> MemoryPropertyFlags

Convert from a bits value exactly.

source

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

Get a flags value with the bits of a flag with the given name set.

This method will return None if name is empty or doesn’t correspond to any named flag.

source

pub const fn is_empty(&self) -> bool

Whether all bits in this flags value are unset.

source

pub const fn is_all(&self) -> bool

The bitwise or (|) of the bits in two flags values.

source

pub fn remove(&mut self, other: 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. remove won’t truncate other, but the ! operator will.

source

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

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

source

pub fn set(&mut self, other: MemoryPropertyFlags, value: bool)

Call insert when value is true or remove when value is false.

source

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

The bitwise and (&) of the bits in two flags values.

source

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

The bitwise or (|) of the bits in two flags values.

source

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.

source

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

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

source

pub const fn complement(self) -> MemoryPropertyFlags

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

source§

impl MemoryPropertyFlags

source

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.

source

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.
