Arbutus
Arbutus is a tree data structure library for Rust.
Overview
Arbutus provides a high-level API for constructing and manipulating trees, along with support for indexing and querying. The library focuses on simplicity, flexibility, and performance.
Features
- Tree Construction: Build trees using the
TreeBuilder
API, which provides a composable way to construct tree structures. - Indexing: Utilize B-Tree indices for efficient querying and retrieval of node data.
- Iterators: Traverse trees using iterators
Getting Started
To get started with Arbutus, add the following dependency to your Cargo.toml
file:
[dependencies]
arbutus = "0.1.0"
Example of building a tree
// Custom errors can be propagated through the builder closures
#[derive(Debug)]
enum MyError {
Fail(String),
}
#[derive(Debug)]
enum TestData {
Foo,
Bar,
String(String),
Baz,
}
let tree = TreeBuilder::<TestData, MyError>::new()
.root(TestData::Foo, |foo| {
debug!("Foo builder closure");
foo.child(TestData::Bar, |bar| {
debug!("Bar builder closure");
bar.child(TestData::Baz, |_| Ok(()))
})?;
foo.child(TestData::String("Hello".into()), |_| Ok(()))?;
Ok(())
})
.unwrap()
.done();
info!("{tree:#?}");
