This library allows you to build a tree one element at a time and output it as a pretty string. This is particularly convenient for generating clean output from nested and recursive functions. A design goal was to allow this library to be used as a drop-in replacement of println!(...).
```rust
extern crate debugtree; use debugtree::defaulttree; fn main() { { addbranch!("{} Branch", "1"); // Enter branch 1 // tree is now pointed inside new branch. addleaf!("{} Child", "1.1"); } // Exit branch because scope ends. addleaf!("2 Sibling"); defaulttree().flushprint(); } ```
1 Branch
└╼ 1.1 Child
2 Sibling
Newlines in multi-line strings are automatically indented. ```rust
extern crate debugtree;
use debugtree::defaulttree;
fn main() {
{
addbranch!("1");
addleaf!("1.1\nNext line");
}
addleaf!(&format!("1.2"));
defaulttree().flushprint();
}
1
├╼ 1.1
│ Next line
└╼ 1.2
```
```rust extern crate debugtree; use debugtree::TreeBuilder; fn main() { // Make a new tree. let tree = TreeBuilder::new();
// Add a scoped branch. The next item added will belong to the branch.
let branch = tree.add_branch("1 Branch");
// Add a leaf to the current branch
tree.add_leaf("1.1 Child");
// Leave scope early
branch.release();
tree.add_leaf("2 Sibling");
tree.flush_print(); // Print and clear.
// default_tree().peek_print(); // Would print but not clear.
}
```
