Struct IndexedTree 

Source 
pub struct IndexedTree<'a, C = Vec<usize>>
where
    C: AsRef<[usize]>,
{ /* private fields */ }
Expand description

A validated zero-copy adapter over an indexed adjacency list.

Implementations§

Source§

impl<'a, C> IndexedTree<'a, C>
where C: AsRef<[usize]>,

Source

pub fn new( roots: impl IntoIterator<Item = usize>, children: &'a [C], revision: TreeRevision, ) -> Result<Self, IndexedTreeError>

Checks bounds, unique parents, and the absence of cycles.

§Errors

Returns IndexedTreeError when a root or child is invalid, a node has multiple parents, the root set is incomplete, or the graph contains a cycle.

Trait Implementations§
