Struct GraphoptOptions 

pub struct GraphoptOptions<'a> {
    pub niter: usize,
    pub node_charge: f64,
    pub node_mass: f64,
    pub spring_length: f64,
    pub spring_constant: f64,
    pub max_sa_movement: f64,
    pub initial: Option<&'a Matrix>,
}

Parameters of the graphopt layout (Graph::layout_graphopt).

The Default uses the original graphopt defaults: 500 iterations, node charge 0.001, node mass 30, spring length 0, spring constant 1, maximum movement 5, and a random start.

Fields

niter: usize

Number of iterations (default 500).

node_charge: f64

Charge of the vertices, for the electric repulsion (default 0.001). With zero charge each iteration is only O(|E|).

node_mass: f64

Mass of the vertices, for the spring forces (default 30).

spring_length: f64

Rest length of the springs (default 0).

spring_constant: f64

Spring constant (default 1).

max_sa_movement: f64

Maximum movement along an axis in a single step (default 5).

initial: Option<&'a Matrix>

Starting positions (n × 2); None starts from a random layout.

Trait Implementations

impl<'a> Clone for GraphoptOptions<'a>

fn clone(&self) -> GraphoptOptions<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for GraphoptOptions<'a>

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

Formats the value using the given formatter.

impl Default for GraphoptOptions<'_>

fn default() -> Self

Returns the “default value” for a type.

impl<'a> PartialEq for GraphoptOptions<'a>

fn eq(&self, other: &GraphoptOptions<'a>) -> 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.
