Struct SugiyamaOptions 

pub struct SugiyamaOptions<'a> {
    pub layers: Option<&'a [i64]>,
    pub hgap: f64,
    pub vgap: f64,
    pub maxiter: usize,
    pub weights: Option<&'a [f64]>,
}

Parameters of the Sugiyama layered layout (Graph::layout_sugiyama).

The Default uses automatic layering, unit gaps, 100 crossing minimization iterations and unit weights.

Fields

layers: Option<&'a [i64]>

Non-negative layer index of every vertex. Empty layers are skipped when minimizing crossings, but keep their room on the y axis. None lets igraph compute a layering, after breaking cycles.

hgap: f64

Preferred minimum horizontal gap between vertices of a layer (default 1).

vgap: f64

Distance between consecutive layers (default 1).

maxiter: usize

Maximum number of iterations of the crossing minimization (default 100).

weights: Option<&'a [f64]>

Edge weights, used only to break cycles: igraph tends to reverse edges with smaller weights.

Implementations

impl<'a> SugiyamaOptions<'a>

pub fn with_layers(self, layers: &'a [i64]) -> Self

Sets the layer of each vertex.

Trait Implementations

impl<'a> Clone for SugiyamaOptions<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for SugiyamaOptions<'a>

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

Formats the value using the given formatter.

impl Default for SugiyamaOptions<'_>

fn default() -> Self

Returns the “default value” for a type.

impl<'a> PartialEq for SugiyamaOptions<'a>

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