Struct gfx_hal::memory::Properties

pub struct Properties { /* fields omitted */ }

Memory property flags.

Methods

impl Properties

pub const DEVICE_LOCAL: Properties

Device local memory on the GPU.

pub const CPU_VISIBLE: Properties

Host visible memory can be accessed by the CPU.

Backends must provide at least one cpu visible memory.

pub const COHERENT: Properties

CPU-GPU coherent.

Non-coherent memory requires explicit flushing.

pub const CPU_CACHED: Properties

Cached memory by the CPU

pub const LAZILY_ALLOCATED: Properties

Memory that may be lazily allocated as needed on the GPU and must not be visible to the CPU.

pub const fn empty() -> Properties

Returns an empty set of flags

pub const fn all() -> Properties

Returns the set containing all flags.

pub const fn bits(&self) -> u16

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u16) -> Option<Properties>

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

pub const fn from_bits_truncate(bits: u16) -> Properties

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

pub const unsafe fn from_bits_unchecked(bits: u16) -> Properties

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: Properties) -> bool

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

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

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

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

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

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