### WIP

- All containers optionally use ArrayPool

- Buffers

  - `DirectAllocationArrayPool`  

    Pretend to have pooling

  - `ArrayPoolFactory`  

    Factory abstraction provides array pool implementation

- Not Sync / Non Concurrent / No Thread Safe

  - `Vec`  

    Reimplemented `List`, can unsafely retrieve the internal Array or as Span, Memory

    *todo* methods same to `List`

- Sync / Concurrent / Thread safe

  - `OnceInit`  

    Similar to `Lazy`, but provides init function when getting  

    Inspired by rust `OnceCell`

- Memories

  - `Box` `ReadOnlyBox`  

    Simply wrap a value onto the heap

  - `ArrayRef` `ReadOnlyArrayRef`  

    A **fat reference** *(`T[] + offset`)* that can be safely put on the **heap**, not a ref struct

  - `MemoryRef` `ReadOnlyMemoryRef`  

    A **fat reference** *(`Memory + offset`)* that can be safely put on the **heap**, not a ref struct

  - `OffsetRef` `ReadOnlyOffsetRef`  

    A **fat reference** *(`object + offset`)* that can be safely put on the **heap**, not a ref struct

  - `MemoryEx`

    - Provides `GetEnumerator` for `Memory` `ReadOnlyMemory`

- Cryptography

  - `AHasher`  

    A hasher that ensures even distribution of each bit  

    If possible use Aes SIMD acceleration (.net7+)
