Enum AddEdgeError

pub enum AddEdgeError {
    SourceMissing,
    TargetMissing,
    BothMissing,
}

Errors that can occur when edges are added to the graph.

Variants specify what exact node is missing.

Variants

SourceMissing

Indicates that the source node is missing from the graph,

TargetMissing

Indicates that the target node is missing form the graph.

BothMissing

Indicates that either node is missing from the graph.

Trait Implementations

impl Clone for AddEdgeError

fn clone(&self) -> AddEdgeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AddEdgeError

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

Formats the value using the given formatter.

impl Hash for AddEdgeError

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 Ord for AddEdgeError

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

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

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for AddEdgeError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for AddEdgeError

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

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl ToString for AddEdgeError

fn to_string(&self) -> String

Converts the given value to a String.

impl Eq for AddEdgeError
