Enum NodeSwapError

pub enum NodeSwapError {
    NodeIdxError(NodeIdxError),
    FirstNodeIsAncestorOfSecond,
    SecondNodeIsAncestorOfFirst,
}

Error variants that can be observed while swapping two subtrees rooted at two nodes of the tree.

Variants

NodeIdxError(NodeIdxError)

At least one of the indices of the roots of the two subtrees is invalid.

FirstNodeIsAncestorOfSecond

The first node is an ancestor of the second node; and hence, the subtrees intersect. The subtrees must be independent to have a valid swap operation.

SecondNodeIsAncestorOfFirst

The second node is an ancestor of the first node; and hence, the subtrees intersect. The subtrees must be independent to have a valid swap operation.

Trait Implementations

impl Clone for NodeSwapError

fn clone(&self) -> NodeSwapError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NodeSwapError

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

Formats the value using the given formatter.

impl From<NodeIdxError> for NodeSwapError

fn from(value: NodeIdxError) -> Self

Converts to this type from the input type.

impl PartialEq for NodeSwapError

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