Struct PageLocation 

pub struct PageLocation {
    pub page_id: u32,
    pub offset: u32,
    pub length: u32,
}

Coordinate of a stored block within the page file — the page that holds it plus the [offset, offset + length) byte window inside that page’s content area. Introduced for ChunkMeta.columnar_page (the columnar-vs-row migration discriminant, PRD #850 Phase 1): a sealed chunk records where its RDCC PageType::ColumnBlock block lives so reads decode the columnar form, while None means a legacy row-stored chunk served by the entity path.

Fields

page_id: u32

Page id holding the block.

offset: u32

Byte offset of the block within that page’s content area.

length: u32

Byte length of the block.

Implementations

impl PageLocation

pub fn new(page_id: u32, offset: u32, length: u32) -> PageLocation

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 Copy for PageLocation

impl Debug for PageLocation

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

Formats the value using the given formatter.

impl Eq for PageLocation

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.
