[−][src]Struct read_tree::PolyTree
A read-only poly-tree data structure.
Similar to Tree
<T>
but allows multiple root nodes.
Methods
impl<T> PolyTree<T>
[src]
ⓘImportant traits for Children<'a, T>pub fn roots(&self) -> Children<T>
[src]
Returns an iterator over the root nodes of the poly-tree.
pub fn get(&self, rank: usize) -> Option<Node<T>>
[src]
Returns the node with the specified rank
.
pub fn len(&self) -> usize
[src]
Returns the number of nodes in the poly-tree.
Because poly-trees are required to not be empty, the length will always
be at least 1
.
pub fn into_sapling(self) -> Sapling<T>
[src]
Turns the poly-tree back into a sapling. No nodes are removed from the tree; building the returned sapling will result in the original poly-tree.
All internal buffers are reused, making this a cheap operation. The only
cost of converting Sapling
<T>
s and PolyTree
<T>
s back and
forth is the validation that occurs during build_polytree
.
