Struct PipelineAsync

pub struct PipelineAsync<'a, Input: Pod, Uniform: Pod, Output: Pod, const N: usize> { /* private fields */ }

This struct represents a pipeline. It is used to run async compute shaders. To build it use the gen_pipeline method of the GpuComputeAsync struct.

Implementations

impl<'a, Input: Pod, Uniform: Pod, Output: Pod, const N: usize> PipelineAsync<'a, Input, Uniform, Output, N>

pub fn write_uniform(&mut self, uniform: &Uniform)

This method is used to write the uniform buffer. It is useful to change the uniform between runs.

pub fn dbg_print_scratchpad<T: Pod + AnyBitPattern + Debug>(&mut self)

This method is used to print the content of the scratchpad buffer. It is useful for debugging.

pub async fn run<T: Send + 'static>( &mut self, input: &Input, workgroups: [(u32, u32, u32); N], callback: impl FnOnce(&Output) -> T + Send, ) -> T

This method is used to run the pipeline. It takes the input buffer, the workgroups and a callback. The callback is used to convert the output buffer to the desired type. It is useful to avoid copying the output buffer. If you want to extract the result you can use a callback like |vals: &[u32; N_ELEMENT]| *vals and the type of return of the callback will be returned as the return of the run function.
