Build Status Coverage Status Crates.io

A Rust library for creating intrusive collections. Currently supports singly-linked and doubly-linked lists, as well as red-black trees.


  • Compatible with #[no_std].
  • Intrusive collections don't require any dynamic memory allocation since they simply keep track of existing objects rather than allocating new ones.
  • You can safely manipulate intrusive collections without any unsafe code.
  • A single object can be a member of multiple intrusive collections simultaneously.
  • Intrusive collections provide a Cursor-based interface, which allows safe mutation while iterating.

For examples and more information, see the documentation (crates.io, master).


Add this to your Cargo.toml:

intrusive-collections = "0.9"

This crate has two Cargo features:

  • nightly: Enables nightly-only features: const fn constructors for collections (Link constructors are always const fn)
  • alloc (enabled by default): Implements IntrusivePointer for Box, Rc and Arc.
