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