Aliased Type§

pub struct TypedStatistics<T> {
    min: Option<<T as DataType>::T>,
    max: Option<<T as DataType>::T>,
    distinct_count: Option<u64>,
    null_count: Option<u64>,

    is_min_value_exact: bool,
    is_min_max_deprecated: bool,
    is_min_max_backwards_compatible: bool,
}

Fields§

§min: Option<<T as DataType>::T>§max: Option<<T as DataType>::T>§distinct_count: Option<u64>§null_count: Option<u64>§is_max_value_exact: bool§is_min_value_exact: bool§is_min_max_deprecated: bool

If true populate the deprecated min and max fields instead of min_value and max_value

§is_min_max_backwards_compatible: bool

If true the statistics are compatible with the deprecated min and max fields. See ValueStatistics::is_min_max_backwards_compatible
