Struct NcolLglOptions 

pub struct NcolLglOptions {
    pub names: bool,
    pub weights: AddWeights,
    pub directed: bool,
}

Options of the NCOL and LGL readers (Graph::read_graph_ncol, Graph::read_graph_lgl).

The defaults are: store names, add weights only if present in the file, undirected graph (the LGL software only handles undirected graphs).

names and weights only matter once the attribute handler is enabled with attributes::enable (see the module docs); without it they are harmless.

Examples

use igraph::{foreign::NcolLglOptions, prelude::*};
let opts = NcolLglOptions::default().with_directed(true).with_weights(AddWeights::No);
assert!(opts.names && opts.directed);
let g = Graph::read_graph_ncol_from_str("a b 2\nb c 3\n", &[], &opts).unwrap();
assert!(g.is_directed());
assert_eq!(g.edge_list(), vec![(0, 1), (1, 2)]);

Fields

names: bool

Whether to store the symbolic vertex names as the name string vertex attribute.

weights: AddWeights

Whether to store the edge weights as the weight numeric edge attribute: AddWeights::Yes always (edges without a weight get 1), AddWeights::IfPresent only if at least one weight is given in the file (again with 1 for the others), AddWeights::No never.

directed: bool

Whether to create a directed graph: the formats carry no information about directedness.

Implementations

impl NcolLglOptions

pub fn with_directed(self, directed: bool) -> Self

Sets directed.

pub fn with_names(self, names: bool) -> Self

Sets names.

pub fn with_weights(self, weights: AddWeights) -> Self

Sets weights.

Trait Implementations

impl Clone for NcolLglOptions

fn clone(&self) -> NcolLglOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NcolLglOptions

impl Debug for NcolLglOptions

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

Formats the value using the given formatter.

impl Default for NcolLglOptions

fn default() -> Self

Returns the “default value” for a type.

impl Eq for NcolLglOptions

impl PartialEq for NcolLglOptions

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