Struct LglOptions 

pub struct LglOptions {
    pub maxiter: usize,
    pub maxdelta: Option<f64>,
    pub area: Option<f64>,
    pub coolexp: f64,
    pub repulserad: Option<f64>,
    pub cellsize: Option<f64>,
    pub root: Option<VertexId>,
}

Parameters of the Large Graph Layout (Graph::layout_lgl).

The Default follows the igraph documentation (n is the number of vertices): 150 iterations, maxdelta = n, area = n², coolexp = 1.5, repulserad = area · n, cellsize = area^(1/4) and a random root.

Fields

maxiter: usize

Maximum number of cooling iterations per layout step (default 150).

maxdelta: Option<f64>

Maximum movement of a vertex in one iteration; None means n.

area: Option<f64>

Area of the square the vertices are placed on; None means n².

coolexp: f64

The cooling exponent (default 1.5).

repulserad: Option<f64>

Radius at which repulsion cancels attraction; None means area · n.

cellsize: Option<f64>

Side of the grid cells; None means the fourth root of area.

root: Option<VertexId>

Root vertex, placed first; None picks a random vertex.

Trait Implementations

impl Clone for LglOptions

fn clone(&self) -> LglOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LglOptions

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

Formats the value using the given formatter.

impl Default for LglOptions

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for LglOptions

fn eq(&self, other: &LglOptions) -> 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.
