pub struct Barrier { /* fields omitted */ }

Memory barrier.

Methods

impl Barrier

pub const VERTEX_ATRRIBUTE_READ: Barrier

pub const INDEX_READ: Barrier

pub const UNIFORM_READ: Barrier

pub const SAMPLED_IMAGE_READ: Barrier

pub const STORAGE_IMAGE_RW: Barrier

pub const INDIRECT_COMMAND_READ: Barrier

pub const PIXEL_BUFFER_RW: Barrier

pub const TEXTURE_TRANSFER: Barrier

pub const BUFFER_TRANSFER: Barrier

pub const FRAMEBUFFER_RW: Barrier

pub const TRANSFORM_FEEDBACK_WRITE: Barrier

pub const ATOMIC_COUNTER_RW: Barrier

pub const STORAGE_BUFFER_RW: Barrier

pub const INPUT_ATTACHMENT_READ: Barrier

Inserts a image (or texture) barrier to control read/write access of fragments in subsequent draw calls.

Image barriers are required to prevent rendering feedback loops in case of reading texels of an image which is bound to the current framebuffer as attachment.

The barrier will ensure that writes to the texel are finished and caches have been invalidated.

pub const ALL: Barrier

pub fn empty() -> Barrier

Returns an empty set of flags.

pub fn all() -> Barrier

Returns the set containing all flags.

pub fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

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

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

pub fn from_bits_truncate(bits: u32) -> Barrier

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

pub fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub fn is_all(&self) -> bool

Returns true if all flags are currently set.

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

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

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

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

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

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

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

impl Copy for Barrier

impl PartialEq<Barrier> for Barrier

fn eq(&self, other: &Barrier) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Barrier) -> bool

This method tests for !=.

impl Clone for Barrier

fn clone(&self) -> Barrier

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Ord for Barrier

fn cmp(&self, other: &Barrier) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Returns max if self is greater than max, and min if self is less than min. Otherwise this will return self. Panics if min > max.
