Agilulf Database Driver (For Rust)

lib.rs:

This is a client of Agilulf KV Server.

Many performance optimization will be done in the future. But now it is simple and fast enough.

The bench in tests of this crate uses MemDatabase to avoid the influence of database algorithm. But as MemDatabase is simply implemented by SkipList, it will cost a lot of RAM.

Two structs are provided to connect with a server:

1. AgilulfClient: The basic client, it will send request and receive response and then return the function (actually return Poll::Ready). Batch send strategy is quite simple: send_all. The response order is kept consistent with request order.

2. MultiAgilulfClient: A client can use multiple TCP Stream. Use multiple TCP Stream at the same time can increase the performance quite well. A MultiAgilulfClient will open multiple AgilulfClient and give them an ID. Any request will be hashed by key and send to corresponding client. As it is a KV server, just keeping operation order consistent of the same key is enough. Note: SCAN is different, this method will affect multiple keys. Guard (just like CPU's Memory Guard) is needed for this operation.
