Implementations

impl BufferUse

pub const MAP_READ: BufferUse

pub const MAP_WRITE: BufferUse

pub const COPY_SRC: BufferUse

pub const COPY_DST: BufferUse

pub const INDEX: BufferUse

pub const VERTEX: BufferUse

pub const UNIFORM: BufferUse

pub const STORAGE_LOAD: BufferUse

pub const STORAGE_STORE: BufferUse

pub const READ_ALL: BufferUse

The combination of all read-only usages.

pub const WRITE_ALL: BufferUse

The combination of all write-only and read-write usages.

pub const ORDERED: BufferUse

The combination of all usages that the are guaranteed to be be ordered by the hardware. If a usage is not ordered, then even if it doesn’t change between draw calls, there still need to be pipeline barriers inserted for synchronization.

pub const fn empty() -> BufferUse

Returns an empty set of flags

pub const fn all() -> BufferUse

Returns the set containing all flags.

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u32) -> Option<BufferUse>

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

pub const fn from_bits_truncate(bits: u32) -> BufferUse

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

pub const unsafe fn from_bits_unchecked(bits: u32) -> BufferUse

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: BufferUse) -> bool

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

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

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

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

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

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