# linked-syntax-tree
[](https://crates.io/crates/linked-syntax-tree)
[](https://docs.rs/linked-syntax-tree)
A doubly-linked syntax tree.
Offers functionality similar to [`std::collections::LinkedList`](https://doc.rust-lang.org/std/collections/struct.LinkedList.html).
Some code:
```text
x = -10
loop
x = x + 1
if x
break
x = 2
```
can be represented as:
```text
┌──────────┐
│x = -10 │
└──────────┘
│
┌──────────┐
│loop │
└──────────┘
│ ╲
┌──────────┐ ┌─────────┐
│x = 2 │ │x = x + 1│
└──────────┘ └─────────┘
│
┌─────────┐
│if x │
└─────────┘
╲
┌─────────┐
│break │
└─────────┘
```
I personally am using this to contain an AST for compile-time evaluate.
