Struct tantivy_columnar::column_values::ColumnStats

pub struct ColumnStats {
    pub gcd: NonZeroU64,
    pub min_value: u64,
    pub max_value: u64,
    pub num_rows: RowId,
}

Column statistics.

Fields

gcd: NonZeroU64

GCD of the elements el - min(column).

min_value: u64

Minimum value of the column.

max_value: u64

Maximum value of the column.

num_rows: RowId

Number of rows in the column.

Implementations

impl ColumnStats

pub fn amplitude(&self) -> u64

Amplitude of value. Difference between the maximum and the minimum value.

Trait Implementations

impl BinarySerializable for ColumnStats

fn serialize<W: Write + ?Sized>(&self, writer: &mut W) -> Result<()>

Serialize

fn deserialize<R: Read>(reader: &mut R) -> Result<Self>

Deserialize

fn num_bytes(&self) -> u64

impl Clone for ColumnStats

fn clone(&self) -> ColumnStats

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnStats

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

Formats the value using the given formatter.

impl PartialEq for ColumnStats

fn eq(&self, other: &ColumnStats) -> 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.

impl Eq for ColumnStats
