Struct OffsetIndexMetaData

pub struct OffsetIndexMetaData {
    pub page_locations: Vec<PageLocation>,
    pub unencoded_byte_array_data_bytes: Option<Vec<i64>>,
}

OffsetIndex information for a column chunk. Contains offsets and sizes for each page in the chunk. Optionally stores fully decoded page sizes for BYTE_ARRAY columns.

Fields

page_locations: Vec<PageLocation>

Vector of PageLocation objects, one per page in the chunk.

unencoded_byte_array_data_bytes: Option<Vec<i64>>

Optional vector of unencoded page sizes, one per page in the chunk. Only defined for BYTE_ARRAY columns.

Implementations

impl OffsetIndexMetaData

pub(crate) fn try_new(index: OffsetIndex) -> Result<Self, ParquetError>

Creates a new OffsetIndexMetaData from an OffsetIndex.

pub fn page_locations(&self) -> &Vec<PageLocation>

Vector of PageLocation objects, one per page in the chunk.

pub fn unencoded_byte_array_data_bytes(&self) -> Option<&Vec<i64>>

Optional vector of unencoded page sizes, one per page in the chunk. Only defined for BYTE_ARRAY columns.

pub(crate) fn to_thrift(&self) -> OffsetIndex

Trait Implementations

impl Clone for OffsetIndexMetaData

fn clone(&self) -> OffsetIndexMetaData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OffsetIndexMetaData

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

Formats the value using the given formatter.

impl HeapSize for OffsetIndexMetaData

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 OffsetIndexMetaData

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