Struct bevy_render::render_phase::RenderCommandState
source · pub struct RenderCommandState<P: PhaseItem + 'static, C: RenderCommand<P>> { /* private fields */ }
Expand description
Wraps a RenderCommand
into a state so that it can be used as a Draw
function.
Therefore the RenderCommand::Param
is queried from the ECS and passed to the command.

and then renders it.
