Enum TaxonomyError 

pub enum TaxonomyError<K> {
    DuplicateEdge(Option<Rc<K>>, Rc<K>),
    DuplicateNode(Rc<K>),
    DuplicateRootNode(Rc<K>),
    DuplicateSubNode(Rc<K>, Rc<K>),

    SourceEqualsDestination,
}

Errors that might occur when managing a taxonomy.

Variants

DuplicateEdge(Option<Rc<K>>, Rc<K>)

Edge (a tuple of a super- and its sub-node) already exists.

DuplicateNode(Rc<K>)

Node is already part of the taxonomy.

DuplicateRootNode(Rc<K>)

Node is already a root-node of the taxonomy.

DuplicateSubNode(Rc<K>, Rc<K>)

Node is already a sub-node of this super-node.

EdgeNotFound(Option<Rc<K>>, Rc<K>)

Edge does not exist in taxonomy.

LoopDetected(Rc<K>)

Operation on this node would create a loop.

NodeHasSubNode(Rc<K>)

Node has at least one sub-node.

NodeNotFound(Rc<K>)

Node not found in taxonomy.

SourceEqualsDestination

Source and destination are equal.

Trait Implementations

impl<K: Clone> Clone for TaxonomyError<K>

fn clone(&self) -> TaxonomyError<K>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<K: Debug> Debug for TaxonomyError<K>

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

Formats the value using the given formatter.

impl<K: PartialEq> PartialEq for TaxonomyError<K>

fn eq(&self, other: &TaxonomyError<K>) -> 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.
