Module parquet::file::statistics

Contains definitions for working with Parquet statistics.

Though some common methods are available on enum, use pattern match to extract actual min and max values from statistics, see below:

use parquet::file::statistics::Statistics;

let stats = Statistics::int32(Some(1), Some(10), None, 3, true);
assert_eq!(stats.null_count(), 3);
assert!(stats.has_min_max_set());
assert!(stats.is_min_max_deprecated());
assert!(stats.min_is_exact());
assert!(stats.max_is_exact());

match stats {
    Statistics::Int32(ref typed) => {
        assert_eq!(*typed.min(), 1);
        assert_eq!(*typed.max(), 10);
    }
    _ => {}
}
