pub struct Graph { /* fields omitted */ }

An undirected graph.

Methods

impl Graph

pub fn nbrs(&self, v: usize) -> Vec<usize>

Create the graph on n vertices with no edge.

pub fn edge(&self, u: usize, v: usize) -> bool

Returns true id uv is an edge.

pub fn connected(&self) -> bool

Returns true if the graph is connected.

impl Graph

pub fn petersen() -> Self

pub fn cycle(n: usize) -> Self

Trait Implementations

impl Flag for Graph

fn induce(&self, p: &[usize]) -> Self

Returns the subflag induced by the vertices in the slice set.

fn name() -> String

A name for this type of flags. For instance "Graphe". This name is used for naming the associated data subdirectory.

fn all_flags(n: usize) -> Vec<Self>

Returns the set of all flags of size n.

fn superflags(&self) -> Vec<Self>

Return the list of flags of size self.size() + 1 that contain self as an induced subflag.

fn generate_next(previous: &[Self]) -> Vec<Self>

Return the list of flags of size self.size() + 1 that contain self as an induced subflag reduced modulo isomorphism.

fn generate(n: usize) -> Vec<Self>

Return the list of flags of size n reduced modulo isomorphism.

fn generate_typed_up(type_flag: &Self, g_vec: &[Self]) -> Vec<Self>

Return the list of flags of g_vec that can be rooted on the flag type_flag. Each different way to root this flag give a different flag in the result.

fn generate_typed(type_flag: &Self, size: usize) -> Vec<Self>

Return the list of flag of size size rooted on type_flag reduced modulo (typed) isomorphism.

fn select_type(&self, eta: &[usize]) -> Self

Reorder self so that the eta.len() first vertices are the values of eta in the corresonding order.

impl Ord for Graph

fn cmp(&self, other: &Graph) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl Clone for Graph

fn clone(&self) -> Graph

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<Graph> for Graph

fn eq(&self, other: &Graph) -> bool

fn ne(&self, other: &Graph) -> bool

This method tests for !=.

impl Eq for Graph

impl PartialOrd<Graph> for Graph

fn partial_cmp(&self, other: &Graph) -> Option<Ordering>

fn lt(&self, other: &Graph) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Graph) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Graph) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Graph) -> bool

    __S: Serializer, 

Serialize this value into the given Serde serializer.

impl<'de> Deserialize<'de> for Graph

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>,
