Today, I will talk to you about how to use Rust to build the TCP/IP protocol stack of the Demikernel operating system from scratch. Many people may not know much about it. In order to make you understand better, the editor has summarized the following for you. I hope you can get something according to this article.

Using rust to implement NES Simulator

The blog post was written using the unstable Rust 1.40 nightly (518deda77). Some unstable functions may have been changed or deleted.

Simulators are good things, they help save the game, improve the game, and help make the game more accessible. Most importantly, making an emulator is a way to vent and meet technical challenges!

Perkv-persistent kv storage (based on Persy 0.7)

This library is a simple persistent general-purpose HashMap/kv storage that uses Persy index API.

It is currently in a testing state.

Use example 1:

Let test_store = perkv::KV::::new (". / basic.cab") .unwrap ()

Let _ = test_store.insert ("key", "value")

Println! ("{:?}", test_store.get ("key"))

Let _ = test_store.remove ("key")

Example 2:

Let test_store = perkv::RawKV::::new (". / raw.cab", "runint") .unwrap ()

Let _ = test_store.insert ("key" .to _ string (), "value" .to _ string ())

Println! ("{:}", test_store.get (& "key" .to _ string ()

Let _ = test_store.remove ("key" .to _ string ()); fancy-regex: a pure rust library for regular expressions with lookups and backreferences

Currently fancy-regex has been updated to version 0.2.0, which is a library built on top of regex crate. It uses a hybrid regex implementation to support a relatively rich set of features. It adds support for advanced features, such as forward / backward lookup and backtracking, which are not supported in purely nfa-based implementations (such as RE2).

After reading the above, do you have any further understanding of how to build the TCP/IP protocol stack of the Demikernel operating system from scratch with Rust? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
