Struct PageLocation

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

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 length

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).

Implementations

impl PageLocation

pub fn new( offset: i64, compressed_page_size: i32, first_row_index: i64, ) -> PageLocation

pub fn read_from_in_protocol<T: TInputProtocol>( i_prot: &mut T, ) -> Result<PageLocation>

pub fn write_to_out_protocol<T: TOutputProtocol>( &self, o_prot: &mut T, ) -> Result<usize>

Trait Implementations

impl Clone for PageLocation

fn clone(&self) -> PageLocation

Returns a copy 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 Hash for PageLocation

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for PageLocation

fn cmp(&self, other: &PageLocation) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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 PartialOrd for PageLocation

fn partial_cmp(&self, other: &PageLocation) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

fn read_from_in_protocol<T: TInputProtocol>( i_prot: &mut T, ) -> Result<PageLocation>
