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:

[dependencies]
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.
