Enum 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>),
}

Statistics for data pages in a column chunk.

See NativeIndex for more information

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>)

Boolean type index

INT32(NativeIndex<i32>)

32-bit integer type index

INT64(NativeIndex<i64>)

64-bit integer type index

INT96(NativeIndex<Int96>)

96-bit integer type (timestamp) index

FLOAT(NativeIndex<f32>)

32-bit floating point type index

DOUBLE(NativeIndex<f64>)

64-bit floating point type index

BYTE_ARRAY(NativeIndex<ByteArray>)

Byte array type index

FIXED_LEN_BYTE_ARRAY(NativeIndex<FixedLenByteArray>)

Fixed length byte array type index

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 HeapSize for Index

fn heap_size(&self) -> usize

Return the size of any bytes allocated on the heap by this object, including heap memory in those structures

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.
