Struct parquet::file::statistics::TypedStatistics

pub struct TypedStatistics<T: DataType> { /* fields omitted */ }

Typed implementation for Statistics.

Implementations

impl<T: DataType> TypedStatistics<T>

pub fn new(
    min: Option<T::T>,
    max: Option<T::T>,
    distinct_count: Option<u64>,
    null_count: u64,
    is_min_max_deprecated: bool
) -> Self

Creates new typed statistics.

pub fn min(&self) -> &T::T

Returns min value of the statistics.

Panics if min value is not set, e.g. all values are null. Use has_min_max_set method to check that.

pub fn max(&self) -> &T::T

Returns max value of the statistics.

Panics if max value is not set, e.g. all values are null. Use has_min_max_set method to check that.

pub fn min_bytes(&self) -> &[u8]

Returns min value as bytes of the statistics.

Panics if min value is not set, use has_min_max_set method to check if values are set.

pub fn max_bytes(&self) -> &[u8]

Returns max value as bytes of the statistics.

Panics if max value is not set, use has_min_max_set method to check if values are set.

Trait Implementations

    T::T: Clone,
    T::T: Clone, 

fn clone(&self) -> TypedStatistics<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
