Enum DispatchError 

pub enum DispatchError {
    NoFamilyMeetsRecall {
        requested: f32,
        best_recall: f32,
        best_family: IndexFamily,
    },
    NoFamiliesEnabled,
}

Errors returned by the dispatcher brain.

Variants

NoFamilyMeetsRecall

No index family in the enabled set met the requested recall, even with fallback disabled.

Fields

requested: f32

Recall floor requested by the caller.

best_recall: f32

Best recall the cost model could project across all enabled families.

best_family: IndexFamily

Family that produced best_recall.
