Blazing fast immutable collection datatypes for Rust.

This is originally a fork of the [`im`](https://github.com/bodil/im-rs) crate, which is unmaintained. The `1.0` release of `imbl` is compatible with the

`15.0.0` release of `im`, but with some fixes to `OrdMap` and `OrdSet`.

Changes from `im` include:

* Bug fixes on OrdMap/OrdSet

* Bug fixes on Vector

* Significant performance improvements for HashMap/HashSet

* Significant performance improvements for OrdMap/OrdSet

* Supports using [`triomphe::Arc`](https://docs.rs/triomphe/latest/triomphe/struct.Arc.html) for the shared pointer implementation

## Documentation

* [API docs](https://docs.rs/imbl/)

## Minimum supported rust version

This crate supports rust 1.77 and later. As const generics become more useful,

the minimum supported rust version will increase.
