//! # Pool implementation providing pre-allocated sub-pools with fixed size memory blocks
//! # Pool implementation providing memory pools for packet storage.
//!
//! This is a simple memory pool implementation which pre-allocates all sub-pools using a given pool
//! configuration. After the pre-allocation, no dynamic memory allocation will be performed
//! during run-time. This makes the implementation suitable for real-time applications and
//! embedded environments. The pool implementation will also track the size of the data stored
//! inside it.
//!
//! Transactions with the [pool][LocalPool] are done using a special [address][StoreAddr] type.
//! Adding any data to the pool will yield a store address. Modification and read operations are
//! done using a reference to a store address. Deletion will consume the store address.
//!
//! # Example
//! # Example for the [StaticMemoryPool]
//!
//! ```
//! use satrs_core::pool::{LocalPool, PoolCfg, PoolProvider};
//! use satrs_core::pool::{PoolProviderMemInPlace, StaticMemoryPool, StaticPoolConfig};
//!
//! // 4 buckets of 4 bytes, 2 of 8 bytes and 1 of 16 bytes
