Struct GemOptions 

pub struct GemOptions<'a> {
    pub maxiter: Option<usize>,
    pub temp_max: Option<f64>,
    pub temp_min: f64,
    pub temp_init: Option<f64>,
    pub initial: Option<&'a Matrix>,
}

Parameters of the GEM layout (Graph::layout_gem).

The Default follows the igraph documentation (n is the number of vertices): 40 n² iterations, temp_max = n, temp_min = 0.1, temp_init = sqrt(n) and a random start.

Fields

maxiter: Option<usize>

Maximum number of iterations (a single vertex update counts as one); None means 40 n².

temp_max: Option<f64>

Maximum local temperature; None means n.

temp_min: f64

Global temperature at which the algorithm stops (default 0.1).

temp_init: Option<f64>

Initial local temperature; None means sqrt(n).

initial: Option<&'a Matrix>

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

Trait Implementations

impl<'a> Clone for GemOptions<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for GemOptions<'a>

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

Formats the value using the given formatter.

impl Default for GemOptions<'_>

fn default() -> Self

Returns the “default value” for a type.

impl<'a> PartialEq for GemOptions<'a>

fn eq(&self, other: &GemOptions<'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.
