Struct vulkano::command_buffer::sys::UnsafeCommandBufferBuilder

pub struct UnsafeCommandBufferBuilder<P> { /* fields omitted */ }

Command buffer being built.

You can add commands to an UnsafeCommandBufferBuilder by using the AddCommand trait. The AddCommand<&Cmd> trait is implemented on the UnsafeCommandBufferBuilder for any Cmd that is a raw Vulkan command.

When you are finished adding commands, you can use the CommandBufferBuild trait to turn this builder into an UnsafeCommandBuffer.

Methods

impl<P> UnsafeCommandBufferBuilder<P>

pub unsafe fn new<Pool, R, F, A>(
    pool: &Pool,
    kind: Kind<R, F>,
    flags: Flags
) -> Result<UnsafeCommandBufferBuilder<P>, OomError> where
    Pool: CommandPool<Builder = P, Alloc = A>,
    P: CommandPoolBuilderAlloc<Alloc = A>,
    A: CommandPoolAlloc,
    R: RenderPassAbstract,
    F: FramebufferAbstract, 

Creates a new builder.

Safety

Creating and destroying an unsafe command buffer is not unsafe per se, but the commands that you add to it are unchecked, do not have any synchronization, and are not kept alive.

In other words, it is your job to make sure that the commands you add are valid, that they don't use resources that have been destroyed, and that they do not introduce any race condition.

Note: Some checks are still made with debug_assert!. Do not expect to be able to submit invalid commands.

pub unsafe fn already_allocated<R, F>(
    alloc: P,
    kind: Kind<R, F>,
    flags: Flags
) -> Result<UnsafeCommandBufferBuilder<P>, OomError> where
    R: RenderPassAbstract,
    F: FramebufferAbstract,
    P: CommandPoolBuilderAlloc, 

Creates a new command buffer builder from an already-allocated command buffer.

Safety

See the new method.

The kind must match how the command buffer was allocated.
