[−][src]Enum read_tree::BuildError

pub enum BuildError<T> {
    Incomplete(Sapling<T>),
    MultipleRoots(Sapling<T>),
}

An error returned when attempting to build a Sapling<T>.

The error contains the sapling that failed to build in order to return it to the caller. Otherwise the build function would drop the sapling without returning a resulting Tree<T>.

Variants

Incomplete(Sapling<T>)

The sapling is incomplete and not ready to be built.

It is either empty or there are still unclosed nodes. Use pop_all to close any unclosed nodes and use is_empty to check if th sapling is empty.

MultipleRoots(Sapling<T>)

The sapling contains more than one root node.

When creating nodes on a sapling it is possible to pop the root node and push a second root. Trees however must have a unique root.

To get an iterator over the root nodes build the sapling into a PolyTree<T> using build_polytree.
