Crate picket 

Picket

Picket is a lightweight, serde-compatible generational arena allocator.

It allows you to insert items into an arena and receive a unique Index in return. Unlike a standard Vec index, a Picket Index contains a “generation” counter. If an item is removed and its slot is reused by a new item, the old Index will fail to access the new item, preventing ABA problems.

Key Features

• Compact: Index contains no padding.
• Serde: Optional support for full serialization/deserialization (feature: serde).
• no_std: Compatible with no_std.
