Struct parquet2::indexes::PageIndex

pub struct PageIndex<T> {
    pub min: Option<T>,
    pub max: Option<T>,
    pub null_count: Option<i64>,
}

The index of a page, containing the min and max values of the page.

Fields

min: Option<T>

The minimum value in the page. It is None when all values are null

max: Option<T>

The maximum value in the page. It is None when all values are null

null_count: Option<i64>

The number of null values in the page

Trait Implementations

impl<T: Clone> Clone for PageIndex<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for PageIndex<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: Hash> Hash for PageIndex<T>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T: PartialEq> PartialEq for PageIndex<T>

fn eq(&self, other: &PageIndex<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
