Enum parquet::file::page_index::index::Index

pub enum Index {
    NONE,
    BOOLEAN(NativeIndex<bool>),
    INT32(NativeIndex<i32>),
    INT64(NativeIndex<i64>),
    INT96(NativeIndex<Int96>),
    FLOAT(NativeIndex<f32>),
    DOUBLE(NativeIndex<f64>),
    BYTE_ARRAY(NativeIndex<ByteArray>),
    FIXED_LEN_BYTE_ARRAY(NativeIndex<FixedLenByteArray>),
}

Typed statistics for a data page in a column chunk. This structure is obtained from decoding the ColumnIndex in the parquet file and can be used to skip decoding pages while reading the file data.

Variants

NONE

Sometimes reading page index from parquet file will only return pageLocations without min_max index, NONE represents this lack of index information

BOOLEAN(NativeIndex<bool>)

INT32(NativeIndex<i32>)

INT64(NativeIndex<i64>)

INT96(NativeIndex<Int96>)

FLOAT(NativeIndex<f32>)

DOUBLE(NativeIndex<f64>)

BYTE_ARRAY(NativeIndex<ByteArray>)

FIXED_LEN_BYTE_ARRAY(NativeIndex<FixedLenByteArray>)

Implementations

impl Index

pub fn is_sorted(&self) -> bool

Return min/max elements inside ColumnIndex are ordered or not.

pub fn get_boundary_order(&self) -> Option<BoundaryOrder>

Get boundary_order of this page index.

Trait Implementations

impl Clone for Index

fn clone(&self) -> Index

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Index

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

Formats the value using the given formatter.

impl PartialEq for Index

fn eq(&self, other: &Index) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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