Struct Sample 

pub struct Sample {
    pub id: String,
    pub family: String,
    pub gold: String,
    pub slots: Vec<String>,
    pub predicted: Option<String>,
    pub probs: Option<Vec<f64>>,
    pub positive: Option<String>,
}

One joined item reduced to exactly the quantities the metrics need.

Fields

id: String

Row id (diagnostics only; the metrics never read it).

family: String

Stratification key, already resolved (None becomes unlabelled).

gold: String

Gold slot key.

slots: Vec<String>

The item’s declared slot keys, in order.

predicted: Option<String>

argmax(probs) when a vector is present, else the row’s label.

probs: Option<Vec<f64>>

Probability vector aligned to slots. None ⇒ row is unscored.

positive: Option<String>

Slot key used as the positive class for brier_binary.
