# pest_ascii_tree
## pest_ascii_tree
This is a small helper crate useful for quickly debugging your pest
grammar.
The rules found by parsing the file are formated into an
[`ascii_tree`].
It is useful, you you want to quickly debug your grammar without
having to write specialized code for handling the `Pairs` iterator
returned by your pest parser.
Example, for whan an output might look like.
<pre>
expr
├─ expr
│ ├─ val "u"
│ ├─ op "+"
│ └─ expr
│ ├─ val "v"
│ ├─ op "+"
│ └─ val "w"
├─ op "+"
├─ expr
│ ├─ val "x"
│ ├─ op "+"
│ └─ val "y"
├─ op "+"
└─ val "z"
</pre>
Please, that the `EOI` rule is skipped.
