Unfortunately it’s implemented on top of std::set/std::map and I’ve had problems with heap blow up on large maps. This project looks like it uses 32 bit indices into a vector for backing store.
I built a project that implemented intervaltree in Rust and exposed PyO3 bindings as a drop-in replacement for Python's native intervaltree. It is significantly faster, and I will be adding more features, such as AVL and red-black trees for balancing.
And with a little work you can even use them to map ranges of keys to values in a way that's reminiscent of interval trees — e.g. https://crates.io/crates/rangemap. (Disclosure: that's my crate.)
Nice! I was only suggesting considering BTrees because they also play nice with caches, instead of the more conventional binary tree balancing mechanisms.
Pretty cool to have this in Rust, might be useful if/when I decide to move some functionality from TS -> Rust.
In the meantime, I have this impelemented in TypeScript in case anyone else will find it useful: https://github.com/ShieldBattery/node-interval-tree
Pretty nice to have this in Rust could come in handy if I decide to migrate some functionality from TypeScript to Rust later on.
In C++ there’s the Boost Interval Container Library, which has an excellent API: https://www.boost.org/doc/libs/latest/libs/icl/doc/html/inde...

What is the native intervaltree, is it [1] you mean? Do you also support the set operations? And can it be pickled safely?

If you want balanced trees, have a look at what Rust's standard library does with BTreeMap.

Will you publish it as a crate too?
