Struct SpatialPage 

pub struct SpatialPage {
    pub header: SpatialPageHeader,
    pub nodes: Vec<NodeRec>,
    pub properties: HashMap<u64, HashMap<String, String>>,
    pub edges: Vec<PageLocalEdge>,
}

A spatial page: header + nodes + properties + edges, packed into a contiguous byte slice.

Fields

header: SpatialPageHeader

nodes: Vec<NodeRec>

properties: HashMap<u64, HashMap<String, String>>

node_id -> properties for nodes in this page.

edges: Vec<PageLocalEdge>

Edges where source node is in this page.

Implementations

impl SpatialPage

pub fn new(morton_prefix: u64, morton_shift: u8) -> Self

Create an empty page with given Morton prefix and shift.

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

Pack this page into a byte vector. Zero-allocation layout: one vec, direct slices.

pub fn unpack(data: &[u8]) -> Result<Self>

Unpack a single spatial page from a byte slice. Zero-copy: nodes and edges are slices.

pub fn find_node_by_id(&self, id: u64) -> Option<usize>

Find a node by its global ID using binary search (nodes are Morton-sorted). O(log n) within the page.

pub fn get_properties(&self, node_id: u64) -> Option<&HashMap<String, String>>

Get properties for a node in this page.

pub fn get_edges_for_node(&self, node_id: u64) -> Vec<&PageLocalEdge>

Get edges where source is a given node in this page.

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

Performs copy-assignment from source.

impl Debug for SpatialPage

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

Formats the value using the given formatter.
