Struct PageLocation 

pub struct PageLocation {
    pub offset: i64,
    pub compressed_page_size: i32,
    pub first_row_index: i64,
}

Page location information for OffsetIndexMetaData

Fields

offset: i64

Offset of the page in the file

compressed_page_size: i32

Size of the page, including header. Sum of compressed_page_size and header

first_row_index: i64

Index within the RowGroup of the first row of the page. When an OffsetIndex is present, pages must begin on row boundaries (repetition_level = 0).

Trait Implementations

impl Clone for PageLocation

fn clone(&self) -> PageLocation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PageLocation

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

Formats the value using the given formatter.

impl HeapSize for PageLocation

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 PageLocation

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

impl<'a, R: ThriftCompactInputProtocol<'a>> ReadThrift<'a, R> for PageLocation

fn read_thrift(prot: &mut R) -> Result<Self>

Read an object of type Self from the input protocol object.

impl WriteThrift for PageLocation

const ELEMENT_TYPE: ElementType = ElementType::Struct

The ElementType to use when a list of this object is written.

fn write_thrift<W: Write>( &self, writer: &mut ThriftCompactOutputProtocol<W>, ) -> Result<()>

Serialize this object to the given writer.

impl WriteThriftField for PageLocation

fn write_thrift_field<W: Write>( &self, writer: &mut ThriftCompactOutputProtocol<W>, field_id: i16, last_field_id: i16, ) -> Result<i16>

Used to write struct fields (which may be primitive or IDL defined types). This will write the field marker for the given field_id, using last_field_id to compute the field delta used by the Thrift compact protocol. On success this will return field_id to be used in chaining.
