Struct Meta 

pub struct Meta {
    pub trained_at: i64,
    pub ham: u64,
    pub spam: u64,
    pub test_ham: u64,
    pub test_spam: u64,
    pub metrics: BTreeMap<String, f64>,

}

What the settings say of the training that made the table.

Fields

trained_at: i64

When it was trained, Unix seconds.

ham: u64

Messages it learned from, by label.

spam: u64

test_ham: u64

Messages it was tested on (the newest), by label.

test_spam: u64

metrics: BTreeMap<String, f64>

Aggregate measures on the test messages, by name (“auc”, “ham_called_spam”…).

device: String

The device it was trained on, as the sharing’s devices name it.

lexicon: Option<SpamWords>

The tokenizer’s words it was trained with (tokenize::Lexicon), which it reads every message with; none in a table made before 8 October 2026, which reads with the packs built in (Table::lexicon).
