Struct CommandBuffer 

pub struct CommandBuffer { /* private fields */ }

Used to send instructions to the GPU.

Implementations

impl CommandBuffer

pub fn record<F: FnOnce()>( &self, flags: CommandBufferUsageFlags, f: F, ) -> Result<(), Error>

Records instructions in the given closure to this command buffer.

Runs begin(), the closure then end().

Examples

cmd_buffer.record(plate::CommandBufferUsageFlags::empty(), || {
    // cmd_buffer.draw(..);
})?;

pub fn begin(&self, flags: CommandBufferUsageFlags) -> Result<(), Error>

Begin recording instructions to this command buffer.

Examples

cmd_buffer.begin(plate::CommandBufferUsageFlags::empty())?;
// cmd_buffer.draw(..);

pub fn end(&self) -> Result<(), Error>

Stop recording instructions to this command buffer.

Examples

// cmd_buffer.draw(..);
cmd_buffer.end()?;

pub fn draw( &self, vert_count: u32, instance_count: u32, first_vert: u32, first_instance: u32, )

Calls a draw command.

To be used when recording a CommandBuffer.

Examples

cmd_buffer.record(plate::CommandBufferUsageFlags::empty(), || {
    cmd_buffer.draw(3, 1, 0, 0);
})?;

pub fn draw_indexed( &self, index_count: u32, instance_count: u32, first_index: u32, vertex_offset: i32, first_instance: u32, )

Calls a draw_indexed command.

To be used when recording a CommandBuffer.

Examples

cmd_buffer.record(plate::CommandBufferUsageFlags::empty(), || {
    cmd_buffer.draw_indexed(3, 1, 0, 0, 0);
})?;
