Enum vulkano::command_buffer::CommandBufferLevel

pub enum CommandBufferLevel {
    Primary,
    Secondary(CommandBufferInheritance),
}

Determines the kind of command buffer to create.

Variants

Primary

Primary command buffers can be executed on a queue, and can call secondary command buffers. Render passes must begin and end within the same primary command buffer.

Secondary(CommandBufferInheritance)

Secondary command buffers cannot be executed on a queue, but can be executed by a primary command buffer. If created for a render pass, they must fit within a single render subpass.

Implementations

impl CommandBufferLevel

pub fn primary() -> CommandBufferLevel

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: Option<QueryControlFlags>,
    query_statistics_flags: QueryPipelineStatisticFlags
) -> CommandBufferLevel

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.

Trait Implementations

impl Clone for CommandBufferLevel

fn clone(&self) -> CommandBufferLevel

Returns a copy of the value.

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

Performs copy-assignment from source.
