Trait BackendTimer 

pub trait BackendTimer {
    type Error;

    // Required method
    fn measure_candidate_ns(
        &mut self,
        program: &Program,
        workgroup_size: [u32; 3],
    ) -> Result<u64, Self::Error>;
}

Backend timing hook used by the generic best-of-N framework.

Required Associated Types

type Error

Error type returned by a concrete timing implementation.

Required Methods

fn measure_candidate_ns( &mut self, program: &Program, workgroup_size: [u32; 3], ) -> Result<u64, Self::Error>
