Enum PagedEntry 

pub enum PagedEntry {
    Local(Cell),
    Overflow(OverflowRef),
}

An on-page entry: either a full local cell, or a pointer to an overflow chain carrying the cell’s body.

Variants

Local(Cell)

Overflow(OverflowRef)

Implementations

impl PagedEntry

pub fn rowid(&self) -> i64

pub fn encode(&self) -> Result<Vec<u8>>

pub fn decode(buf: &[u8], pos: usize) -> Result<(PagedEntry, usize)>

Dispatches on the kind tag and returns the appropriate variant.

Only KIND_LOCAL and KIND_OVERFLOW are valid here — PagedEntry is the table-leaf-cell type, so any other kind means a caller pointed the wrong decoder at this page (the slot directory layout is shared across leaf B-Trees, but secondary-index, HNSW, and FTS leaves carry kind-specific cells decoded by IndexCell::decode, HnswNodeCell::decode, and FtsPostingCell::decode respectively). The named-kind error makes that mistake obvious next time.

Trait Implementations

impl Clone for PagedEntry

fn clone(&self) -> PagedEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PagedEntry

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

Formats the value using the given formatter.

impl PartialEq for PagedEntry

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