Struct gpu_alloc::MemoryPropertyFlags

pub struct MemoryPropertyFlags { /* fields omitted */ }

Memory properties type.

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.

pub const fn empty() -> MemoryPropertyFlags

Returns an empty set of flags

pub const fn all() -> MemoryPropertyFlags

Returns the set containing all flags.

pub const fn bits(&self) -> u8

Returns the raw value of the flags currently stored.

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

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

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

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const unsafe fn from_bits_unchecked(bits: u8) -> MemoryPropertyFlags

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

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

Returns true if there are flags common to both self and other.

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

Returns true all of the flags in other are contained within self.

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

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

Inserts or removes the specified flags depending on the passed value.
