Module parquet::file::statistics

source ·
Expand description

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);
    }
    _ => {}
}
