Enum GraphFormat 

pub enum GraphFormat {
    Edgelist,
    Ncol,
    Lgl,
    Pajek,
    GraphMl,
    Gml,
    DimacsFlow,
    GraphDb,
    Dl,
    Dot,
    Leda,
}

Graph file formats known to igraph, for the format-agnostic Graph::read_graph and Graph::write_graph.

The variants list the file extensions recognized by from_path; can_read and can_write tell which direction the generic functions support.

Variants

Edgelist

Plain edge list of 0-based vertex ids (.txt, .edgelist, .edges, .el).

Ncol

NCOL symbolic edge list (.ncol).

Lgl

LGL format (.lgl).

Pajek

Pajek (.net, .pajek).

GraphMl

GraphML (.graphml, .xml).

Gml

GML (.gml).

DimacsFlow

DIMACS flow format (.dimacs, .max); only Graph::read_graph supports it generically (it discards the problem data).

GraphDb

Binary ARG graph database format (.graphdb, and the .A00….A99, .B00….B99 suffixes of the database’s graph pairs); read only.

Dl

UCINET DL (.dl); read only.

Dot

Graphviz DOT (.dot, .gv); write only.

Leda

LEDA native format (.gw, .leda); write only.

Implementations

impl GraphFormat

pub fn from_path(path: impl AsRef<Path>) -> Option<Self>

Guesses the format from the extension of path (case insensitive), or None if the extension is unknown.

use igraph::foreign::GraphFormat;
assert_eq!(GraphFormat::from_path("karate.GML"), Some(GraphFormat::Gml));
assert_eq!(GraphFormat::from_path("/tmp/g.net"), Some(GraphFormat::Pajek));
assert_eq!(GraphFormat::from_path("noext"), None);

pub fn can_read(self) -> bool

Whether igraph can read this format.

pub fn can_write(self) -> bool

Whether igraph can write this format (DIMACS needs extra data: use Graph::write_graph_dimacs_flow directly).

Trait Implementations

impl Clone for GraphFormat

fn clone(&self) -> GraphFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for GraphFormat

impl Debug for GraphFormat

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

Formats the value using the given formatter.

impl Eq for GraphFormat

impl Hash for GraphFormat

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for GraphFormat

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