Implementations

impl Barrier

pub const VERTEX_ATTRIBUTE_READ: Barrier

Read access to a vertex buffer.

Bound via bind_vertex_buffers, used in drawing commands.

pub const INDEX_READ: Barrier

Read access to an index buffer.

Bound via bind_index_buffer, used in indexed drawing commands.

pub const UNIFORM_READ: Barrier

Read access to a uniform buffer.

Bound via bind_uniform_buffers.

pub const SAMPLED_IMAGE_READ: Barrier

Read access to a sampled image.

Bound via bind_image_views.

pub const STORAGE_IMAGE_RW: Barrier

Read/Write access to a storage image.

Bound via bind_storage_image_views.

pub const INDIRECT_COMMAND_READ: Barrier

Read access to an indirect command buffer.

Bound via bind_draw_indirect_buffer or bind_dispatch_indirect_buffer.

pub const BUFFER_IMAGE_TRANSFER_RW: Barrier

Read/write access to a buffer in transfer operations to/from images or attachments.

Used in copy_attachment_to_buffer and copy_buffer_to_image.

pub const IMAGE_TRANSFER_RW: Barrier

Read/write access to an image in transfer operation.

pub const BUFFER_TRANSFER_RW: Barrier

Read/write access to an buffer in a transfer operation and mapping operations.

pub const FRAMEBUFFER_RW: Barrier

Read/write access to framebuffer attachments.

pub const TRANSFORM_FEEDBACK_WRITE: Barrier

pub const ATOMIC_COUNTER_RW: Barrier

Read/write access to atomic counters.

pub const STORAGE_BUFFER_RW: Barrier

Read/write access to storage buffers.

Bound via bind_storage_buffers.

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 const fn empty() -> Barrier

Returns an empty set of flags

pub const fn all() -> Barrier

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<Barrier>

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) -> Barrier

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

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

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: Barrier) -> bool

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

pub const 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.
