Concept definition

template<typename R, typename P, typename Scalar, typename G>
concept ResamplerUnder =
    ExecutionPolicy<P>
    && requires(R const & r, P && policy, std::span<Scalar const> weights, std::span<Eigen::Index> ancestors, G & rng) {

       }

Detailed Description

A Resampler that also runs under the execution policy P, called as r(policy, weights, ancestors, rng).

ParticleSet::resample() under a policy calls a resampler this way if it can, and as a plain Resampler otherwise.
