Implementations

impl AccessFlags

pub const INDIRECT_COMMAND_READ: VkAccessFlags = 1u32

Specifies read access to an indirect command structure read as part of an indirect drawing or dispatch command.

pub const INDEX_READ: VkAccessFlags = 2u32

Specifies read access to an index buffer as part of an indexed drawing command, bound by vkCmdBindIndexBuffer.

pub const VERTEX_ATTRIBUTE_READ: VkAccessFlags = 4u32

Specifies read access to a vertex buffer as part of a drawing command, bound by vkCmdBindVertexBuffers.

pub const UNIFORM_READ: VkAccessFlags = 8u32

Specifies read access to a uniform buffer.

pub const INPUT_ATTACHMENT_READ: VkAccessFlags = 16u32

Specifies read access to an input attachment within a render pass during fragment shading.

pub const SHADER: Self

Specifies read/write access to a storage buffer, uniform texel buffer(read only), storage texel buffer, samples image(read only), or storage image.

pub const COLOR_ATTACHMENT: Self

• read: Specifies read access to a color attachment, such as via blending, logic operations, or via certain subpass load operations.
• write: specifies write access to a color or resolve attachment during a render pass or via certain subpass load and store operations.

pub const DEPTH_STENCIL_ATTACHMENT: Self

• read: Specifies read access to a depth/stencil attachment, via depth or stencil operations or via certain subpass load operations.
• write: Specifies write access to a depth/stencil attachment, via depth or stencil operations or via certain subpass load and store operations.

pub const TRANSFER: Self

Specifies read/write access to an image or buffer in a clear(write only) or copy operation.

pub const HOST: Self

Specifies read/write access by a host operation. Accesses of this type are not performed through a resource, but directly on memory.

pub const MEMORY: Self

Specifies read/write access via non-specific entities. These entities include the Vulkan device and host, but may also include entities external to the Vulkan device or otherwise not part of the core Vulkan pipeline.

• When the write mask included in a source access mask, all writes that are performed by entities known to the Vulkan device are made available.
• When included in a destination access mask, makes all available writes visible to all future read accesses on entities known to the Vulkan device.
