Struct StatSankey 

pub struct StatSankey {
    pub node_width: f64,
    pub node_padding: f64,
    pub justify: bool,
    pub iterations: usize,
}

Sankey layout stat behind GeomSankey.

Fields

node_width: f64

Node width in column units (columns are 1 apart).

node_padding: f64

Vertical gap between nodes as a fraction of the tallest column’s flow.

justify: bool

Move nodes without outgoing links to the last column (d3’s sankeyJustify); false keeps them at their depth.

iterations: usize

Barycentre sweeps used to reorder nodes (0 keeps first-appearance order).

Trait Implementations

impl Clone for StatSankey

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StatSankey

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

Formats the value using the given formatter.

impl Default for StatSankey

fn default() -> Self

Returns the “default value” for a type.

impl Stat for StatSankey

fn panelwise(&self) -> bool

The layout needs every link of the panel at once.

fn compute_group(&self, data: &DataFrame, _scales: &ScaleSet) -> DataFrame

Transform data for a single group.

fn required_aes(&self) -> Vec<Aesthetic>

Required aesthetics this stat needs.

fn name(&self) -> &str

Name for debug/display.

fn default_aes(&self) -> Aes

Default aesthetic mappings this stat produces.

fn validate(&self, _warnings: &mut Vec<String>)

Validate the stat’s own fixed configuration (not the data) and push a human-readable warning for each problem found — e.g. StatBinHex::binwidth being NaN, zero or negative. Called once per layer, before compute_group runs (which has no warnings channel of its own: the per-group call only sees &DataFrame and &ScaleSet, not the plot’s warnings sink). Default: no-op.
