Trait GaussianModePosteriorSampler 

Source 
pub trait GaussianModePosteriorSampler: Send + Sync {
    // Required method
    fn sample_gaussian_mode_posterior(
        &self,
        mode: ArrayView1<'_, f64>,
        precision: ArrayView2<'_, f64>,
    ) -> Result<GaussianModePosterior, String>;
}
Expand description

The gam-inference-tier sampler for the never-fail Gaussian mode posterior (custom-family covariance escalation). Implemented UP over hmc_io::sample_gaussian_mode_posterior (which auto-derives its NutsConfig::for_dimension(mode.len()) internally — that NUTS config never crosses the contract) and injected DOWN via set_gaussian_mode_posterior_sampler.

Required Methods§

Source

fn sample_gaussian_mode_posterior( &self, mode: ArrayView1<'_, f64>, precision: ArrayView2<'_, f64>, ) -> Result<GaussianModePosterior, String>

Sample N(mode, precision⁻¹). Err only for a structurally impossible request (dimension mismatch, non-PSD precision after symmetrization) — never for “did not converge”.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
