Trait TrialExecutor 

pub trait TrialExecutor: Send + Sync {
    // Required method
    fn execute_trial(
        &self,
        params: &HashMap<String, Value>,
        ctx: &TrialContext,
    ) -> Result<TrialOutcome>;
}

Callback that executes a trial given sampled parameters.

Returns Ok(TrialOutcome) for normal completion or pruning, Err(SomaError) only for unexpected failures.

Required Methods

fn execute_trial( &self, params: &HashMap<String, Value>, ctx: &TrialContext, ) -> Result<TrialOutcome>

Run one trial with the sampled params, reporting intermediate metrics through ctx and honouring its pruning verdicts.

Dyn Compatibility

This trait is dyn compatible.

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