    InvalidWeight,
    CycleError,
    CouldNotRender,
    InvalidGraphName,
}

Graph operation error

Variants

NoSuchVertex

There is no vertex with the given id in the graph

NoSuchEdge

There is no such edge in the graph

CannotAddEdge

Could not add an edge to the graph

InvalidWeight

The given weight is invalid

CycleError

The operation cannot be performed as it will create a cycle in the graph.

CouldNotRender

Could not render .dot file

InvalidGraphName

The name of the graph is invalid. Check this out for more information.

Trait Implementations

impl Clone for GraphErr

fn clone(&self) -> GraphErr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GraphErr

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

Formats the value using the given formatter.

impl PartialEq for GraphErr

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