Enum Command

pub enum Command {
    Draw(Box<dyn DrawCommand>),
    Compute(Box<dyn ComputeCommand>),
}

Unified command enum that can represent either a draw or compute operation.

This enum enables the rendering system to process both graphics and compute commands in a unified pipeline, with proper barrier handling for multi-pass rendering scenarios.

Examples

// Creating a draw command
let draw_cmd = Command::Draw(Box::new(ShapeCommand::Rect { /* ... */ }));

// Creating a compute command
let compute_cmd = Command::Compute(Box::new(BlurCommand { /* ... */ }));

Variants

Draw(Box<dyn DrawCommand>)

A graphics rendering command processed by draw pipelines

Compute(Box<dyn ComputeCommand>)

A GPU computation command processed by compute pipelines

Implementations

impl Command

pub fn barrier(&self) -> Option<BarrierRequirement>

Returns the barrier requirement for this command.

Commands that need to sample from previously rendered content should return a barrier requirement to ensure proper synchronization.
