Struct CsrMutableEdges 

pub struct CsrMutableEdges { /* private fields */ }

Mutable edge storage combining CSR base with delta slab

Provides efficient edge mutations with automatic rebuild when delta grows too large.

Implementations

impl CsrMutableEdges

pub fn new() -> Self

Create new mutable edges with empty base

pub fn with_coords(coords: Vec<PackedCoord>) -> Self

Create with initial vertex coordinates

pub fn add_edge(&mut self, from: VertexId, to: VertexId)

Add an edge, rebuilding if threshold reached

pub fn remove_edge(&mut self, from: VertexId, to: VertexId)

Remove an edge, rebuilding if threshold reached

pub fn out_edges(&self, v: VertexId) -> Vec<VertexId>

Get outgoing edges for a vertex (merged view)

pub fn in_edges(&self, v: VertexId) -> &[VertexId]

Get incoming edges from base CSR (delta not applied for performance) After rebuild, this will include all changes

pub fn delta_size(&self) -> usize

Get the current delta size

pub fn rebuild(&mut self)

Force a rebuild of the CSR structure

pub fn begin_batch(&mut self)

Enter batch mode - defer rebuilds until end_batch() is called

pub fn end_batch(&mut self)

Exit batch mode and rebuild if needed

pub fn add_vertex(&mut self, coord: PackedCoord, vertex_id: u32) -> usize

Add a new vertex with its coordinate and ID

pub fn add_vertices_batch(&mut self, items: &[(PackedCoord, u32)])

Add many vertices at once; single rebuild at end.

pub fn update_coord(&mut self, vertex_id: VertexId, new_coord: PackedCoord)

Update coordinate for a vertex in the cache Marks for rebuild to maintain sort order

pub fn build_from_adjacency( &mut self, adjacency: Vec<(u32, Vec<u32>)>, coords: Vec<PackedCoord>, vertex_ids: Vec<u32>, )

Build underlying CSR directly from adjacency and provided coords/ids. This replaces the current base and clears the delta slab.

Trait Implementations

impl Debug for CsrMutableEdges

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

Formats the value using the given formatter.

impl Default for CsrMutableEdges

fn default() -> Self

Returns the “default value” for a type.
