Trait Proposer 

Source 
pub trait Proposer {
    // Required method
    fn propose(
        &mut self,
        knobs: &[CalibrationKnob],
        current_loss: (f64, f64),
        history: &[StepReport],
    ) -> Option<ProposedPatch>;
}
Expand description

Strategy for choosing the next knob + value to try.

Implementations receive the current knob state, the multi-seed loss observation, and the history. They return None when they have nothing more to propose (the loop then stops). The default [BoundsScanProposer] cycles through knobs proposing current ± max_step in the direction that improved the loss most recently; an AutoTuner-driven proposer is a Piece 2.5 follow-up.

Required Methods§

Source

fn propose( &mut self, knobs: &[CalibrationKnob], current_loss: (f64, f64), history: &[StepReport], ) -> Option<ProposedPatch>

Dyn Compatibility§

This trait is dyn compatible.

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