Blazing fast immutable collection datatypes for Rust.

This is originally a fork of the im 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 for the shared pointer implementation

• API docs

This crate supports rust 1.77 and later. As const generics become more useful, the minimum supported rust version will increase.
