How to use GraphicsPipelineAbstract in the draw_indexed function

[SiebenCorgie]

Hi

I tried to store a GraphicsPipeline in a struct. As suggested here I tried to use the GraphicsPipelineAbstract in a struct like

pub struct pipe_def{
    name: String,
    pipeline: Arc<pipeline::GraphicsPipelineAbstract>,
}

However if I pass this to the function draw_indexed I get the following error:

error[E0277]: the trait bound `vulkano::pipeline::GraphicsPipelineAbstract: std::marker::Send` is not satisfied
   --> src/main.rs:254:22

    = note: required because of the requirements on the impl of `std::marker::Send` for `std::sync::Arc<vulkano::pipeline::GraphicsPipelineAbstract>`

    = note: required because of the requirements on the impl of `std::marker::Send` for `std::sync::Arc<vulkano::pipeline::GraphicsPipelineAbstract>`

Any way to fix this?

thanks in advance,

Hi,

Try Arc<GraphicsPipelineAbstract + Send + Sync> instead of simply Arc<GraphicsPipelineAbstract>.

Works like a charm,
thank you very much!
