Trait ColdStartPlanner 

Source 
pub trait ColdStartPlanner {
    // Required methods
    fn initial_plan(&mut self, state: &dyn StateView) -> ColdStartPlan;
    fn on_results(
        &mut self,
        results: &ColdStartResults,
        state: &dyn StateView,
    ) -> ColdStartStep;
}
Expand description

Drives a bounded multi-round cold start.

The driver calls initial_plan once, executes it, then repeatedly calls on_results with the round’s results and the post-injection StateView; a returned ColdStartStep::Continue is run as the next round and ColdStartStep::Done ends the run. The loop is bounded by ColdStartConfig::max_rounds.

Implementations perform no IO — the trait hands them only borrowed, read-only state, so all fetching is the driver’s responsibility.

Required Methods§

Source

fn initial_plan(&mut self, state: &dyn StateView) -> ColdStartPlan

The first plan to execute, derived from the current cached state.

Source

fn on_results( &mut self, results: &ColdStartResults, state: &dyn StateView, ) -> ColdStartStep

Decide whether to continue (with a next plan) or finish, given the just- completed round’s results and the post-injection state view.

Dyn Compatibility§

This trait is dyn compatible.

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