Arena-rs

An arena memory pool for fast Rust heap allocations and dealocations.

This allows data to be allocated instantly and destroyed in batches.

Creating an Arena

rust let mut arena = Arena::new(1024 /* size in bytes*/);

Allocating data

rust let value = arena.alloc(17)?; assert_eq!(*value, 17);

Deallocating data

rust { let arena = Arena::new(1024); } // <- All data in arena is deallocated here

Saftey

rust let arena = Arena::new(1024); let value = arena.alloc(17)?; move_arena(arena); println!("{}", *value); // <- Compiler Error // The arena was destroyed when we gave it to `move_arena` // so we cannot use any data it gave to us
