Struct FtrlResourceDiagnostics 

pub struct FtrlResourceDiagnostics {
    pub current_features: usize,
    pub configured_max: Option<usize>,
    pub saturation: Option<f64>,
    pub new_features_rejected: bool,
}

Bounded-resource diagnostics for a sparse FTRL model.

saturation is current_features / configured_max when a finite cap is configured. new_features_rejected means that the configured Reject policy would reject another unseen feature at the current size; it is a current admission signal, not a hidden mutation counter.

Fields

current_features: usize

Number of distinct feature identifiers currently stored.

configured_max: Option<usize>

Configured maximum number of stored feature identifiers.

saturation: Option<f64>

Current feature count divided by the configured maximum.

new_features_rejected: bool

Whether an unseen feature would be rejected under the current policy.
