Fields

name: String

ty: String

null_count: u64

value_count: u64

distinct_count: Option<u64>

None if cardinality exceeded opts.distinct_limit, OR the field type isn’t hashable (floats — see module docs).

min: Option<JsonValue>

String/JSON representation of min / max — see value_to_json_repr.

max: Option<JsonValue>

top_values: Vec<TopValue>

Top-N most frequent values (descending by count). Empty for float-typed or over-cardinality fields.
