Enum vulkano::command_buffer::sys::Kind

pub enum Kind<R, F> {
    Primary,
    Secondary {
        render_pass: Option<KindSecondaryRenderPass<R, F>>,
        occlusion_query: KindOcclusionQuery,
        query_statistics_flags: QueryPipelineStatisticFlags,
    },
}

Determines the kind of command buffer that we want to create.

Variants

Primary

A primary command buffer can execute all commands and can call secondary command buffers.

Secondary

Fields

render_pass: Option<KindSecondaryRenderPass<R, F>>

If Some, can only call draw operations that can be executed from within a specific subpass. Otherwise it can execute all dispatch and transfer operations, but not drawing operations.

occlusion_query: KindOcclusionQuery

Whether it is allowed to have an active occlusion query in the primary command buffer when executing this secondary command buffer.

query_statistics_flags: QueryPipelineStatisticFlags

Which pipeline statistics queries are allowed to be active when this secondary command buffer starts.

Note that the pipeline_statistics_query feature must be enabled if any of the flags of this value are set.

A secondary command buffer.

Implementations

impl Kind<RenderPass<EmptySinglePassRenderPassDesc>, Framebuffer<RenderPass<EmptySinglePassRenderPassDesc>, ()>>

pub fn primary(
) -> Kind<Arc<RenderPass<EmptySinglePassRenderPassDesc>>, Framebuffer<RenderPass<EmptySinglePassRenderPassDesc>, ()>>

Equivalent to Kind::Primary.

Note: If you use let kind = Kind::Primary; in your code, you will probably get a compilation error because the Rust compiler couldn’t determine the template parameters of Kind. To solve that problem in an easy way you can use this function instead.

pub fn secondary(
    occlusion_query: KindOcclusionQuery,
    query_statistics_flags: QueryPipelineStatisticFlags
) -> Kind<Arc<RenderPass<EmptySinglePassRenderPassDesc>>, Framebuffer<RenderPass<EmptySinglePassRenderPassDesc>, ()>>

Equivalent to Kind::Secondary.

Note: If you use let kind = Kind::Secondary; in your code, you will probably get a compilation error because the Rust compiler couldn’t determine the template parameters of Kind. To solve that problem in an easy way you can use this function instead.
