Struct ConversationMetrics 

pub struct ConversationMetrics {
    pub context_retention: f64,
    pub goal_completion: f64,
    pub coherence: f64,
    pub topic_drift: f64,
}

Available on crate feature eval only.

Multi-turn conversation quality metrics.

All scores are in the range [0.0, 1.0].

Fields

context_retention: f64

Score measuring whether the agent correctly references information from prior turns (0.0–1.0).

goal_completion: f64

Score measuring whether the agent achieves the stated objective across the conversation (0.0–1.0).

coherence: f64

Score measuring logical consistency between consecutive agent responses (0.0–1.0).

topic_drift: f64

Score measuring deviation from original topic (0.0–1.0, where 1.0 indicates no drift).
