Struct TrackingLeafNode 

pub struct TrackingLeafNode {
    pub keys: Vec<String>,
    pub values: Vec<Position>,
}

A simple leaf-only node for the tracking tree. Keys are UTF-8 source strings; values are positions.

Fields

keys: Vec<String>

values: Vec<Position>

Implementations

impl TrackingLeafNode

pub fn new() -> Self

pub fn calc_serialized_size(&self) -> usize

pub fn serialize_into(&self, buf: &mut [u8]) -> DcbResult<usize>

pub fn from_slice(slice: &[u8]) -> DcbResult<Self>

pub fn get(&self, source: &str) -> Option<Position>

pub fn upsert_no_split( &mut self, source: &str, pos: Position, page_body_capacity: usize, ) -> DcbResult<()>

Insert or update a key with value while enforcing page size limit (no splitting). Returns Err(InternalError(“not implemented: tracking split”)) if it would exceed page capacity.
