Recursive helper?

[matthiasbeyer]

Hi,

would it be possible to build a recursive helper for recursing on a tree-like structure?

E.G.:

{{recurse_with element.children tree}}
print something for {{element.value}}
{{/recurse_with}}

For a tree structure where

struct Tree {
  value: String,
  children: Vec<Tree>
}

For example? The first argument of the recurse_with helper would be a selector that gets the list of children nodes from a node.

---

To expand on that, I would like to implement depth-first and breadth-first recursion, but that shouldn't be too complicated if the basic helper is implemented.

Argh,... my problem is actually not a tree structure, but a BTreeMap<Key, Value> where each value holds a list of Keys that are also in the map.
So, I actually do not need a recursive tree helper, but something different.

I'll leave this open anyways, it might be interesting for others.
