Struct ForceDirectedLayout 

pub struct ForceDirectedLayout {
    pub config: LayoutConfig,
    pub converged: bool,
    /* private fields */
}

Force-directed graph layout engine.

Fields

config: LayoutConfig

Configuration.

converged: bool

Whether layout has converged.

Implementations

impl ForceDirectedLayout

pub fn new(config: LayoutConfig) -> Self

Create a new layout engine.

pub fn initialize(&mut self, network: &AccountingNetwork)

Initialize layout from accounting network.

pub fn step(&mut self) -> bool

Run one iteration of the layout algorithm.

pub fn iterate(&mut self, iterations: usize)

Run multiple iterations.

pub fn get_position(&self, index: u16) -> Option<Vector2<f32>>

Get node position.

pub fn nodes(&self) -> impl Iterator<Item = &LayoutNode>

Get all nodes.

pub fn edges(&self) -> &[(u16, u16, f32)]

Get all edges.

pub fn pin_node(&mut self, index: u16)

Pin a node at its current position.

pub fn unpin_node(&mut self, index: u16)

Unpin a node.

pub fn set_position(&mut self, index: u16, position: Vector2<f32>)

Set node position (for dragging).

pub fn resize(&mut self, width: f32, height: f32)

Resize the layout area.

pub fn reset(&mut self, network: &AccountingNetwork)

Reset the layout.

pub fn update_edges(&mut self, network: &AccountingNetwork)

Update edge weights from network without resetting positions. This allows the layout to adapt to new flow data while preserving node positions.

pub fn warm_up(&mut self)

Warm up the layout to allow it to readjust. Call this periodically to let the layout adapt to weight changes.

pub fn has_edges(&self) -> bool

Check if layout has any edges.

pub fn edge_count(&self) -> usize

Get edge count.

Trait Implementations

impl Default for ForceDirectedLayout

fn default() -> Self

Returns the “default value” for a type.
