Struct sierra::MemoryUsage

pub struct MemoryUsage { /* fields omitted */ }

Memory usage type. Bits set define intended usage for requested memory.

Implementations

impl MemoryUsage

pub const DOWNLOAD: MemoryUsage

Hints allocator that memory will be used for data downloading. Allocator will strongly prefer host-cached memory. Implies HOST_ACCESS flag.

pub const UPLOAD: MemoryUsage

Hints allocator that memory will be used for data uploading. If DOWNLOAD flag is not set then allocator will assume that host will access memory in write-only manner and may pick not host-cached. Implies HOST_ACCESS flag.

pub const FAST_DEVICE_ACCESS: MemoryUsage

Hints for device to find memory with fast device access.

pub const fn empty() -> MemoryUsage

Returns an empty set of flags

pub const fn all() -> MemoryUsage

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<MemoryUsage>

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) -> MemoryUsage

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

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

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: MemoryUsage) -> bool

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

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

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

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

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

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