distant/distant-core

distant core

Library that powers the distant binary.

🚧 (Alpha stage software) This library is in rapid development and may break or change frequently! 🚧

Details

The distant library supplies a mixture of functionality and data to run servers that operate on remote machines and clients that talk to them.

• Asynchronous in nature, powered by tokio
• Data is serialized to send across the wire via CBOR
• Encryption & authentication are handled via XChaCha20Poly1305 for an authenticated encryption scheme via RustCrypto/ChaCha20Poly1305

Installation

You can import the dependency by adding the following to your Cargo.toml:

[dependencies]
distant-core = "0.15"

Features

Currently, the library supports the following features:

• structopt: generates StructOpt bindings for RequestData (used by cli to expose request actions)

By default, no features are enabled on the library.

Examples

Below is an example of connecting to a distant server over TCP:

use distant_core::{Session, SessionChannelExt, SecretKey32, XChaCha20Poly1305Codec};
use std::net::SocketAddr;

// 32-byte secret key paresd from hex, used for a specific codec
let key: SecretKey32 = "DEADBEEFDEADBEEFDEADBEEFDEADBEEFDEADBEEFDEADBEEFDEADBEEFDEADBEEF".parse().unwrap();
let codec = XChaCha20Poly1305Codec::from(key);

let addr: SocketAddr = "example.com:8080".parse().unwrap();
let mut session = Session::tcp_connect(addr, codec).await.unwrap();

// Append text to a file, representing request as <tenant>
// NOTE: This method comes from SessionChannelExt
session.append_file_text(
    "<tenant>", 
    "path/to/file.txt".to_string(), 
    "new contents"
).await.expect("Failed to append to file");
