ghast-client 0.2.0

//! Headless Minecraft Java Edition client for the ghast library.
//!
//! - [`Client`]: connect (directly or through a SOCKS5 proxy, see [`ghast_auth::connect`]),
//!   handshake, login (offline; online mode with the `microsoft` feature), compression and
//!   encryption, then the play state: keep-alives, teleports, window confirms, health,
//!   respawn, chat.
//! - A fixed 50 ms tick loop with vanilla 1.8.9's tick order (see [`engine`](crate::TickContext)
//!   for the details): inbound packets → [`Behavior::tick`] (actions written immediately) →
//!   rotation → movement → exactly one movement packet.
//! - A version-agnostic API: behaviours see [`TickContext`] and the types of [`common`],
//!   never packets. The connection is generic over the protocol version
//!   ([`version::ClientVersion`]), so each supported version is monomorphised.
//! - Packets nobody needs are dropped before they are decoded; a behaviour opts into more
//!   with [`Behavior::interests`].
//!
//! Supported versions: 1.8.9 (protocol 47) and 1.16.5 (protocol 754).
//!
//! ```no_run
//! use ghast_client::{Account, Behavior, Client, GameVersion, Interests, TickContext};
//!
//! struct Echo;
//! impl Behavior for Echo {
//!     fn interests(&self) -> Interests {
//!         Interests::CHAT
//!     }
//!     fn tick(&mut self, ctx: &mut TickContext<'_>) {
//!         let lines: Vec<String> = ctx.events().chat.iter().map(|m| m.plain()).collect();
//!         for line in lines {
//!             println!("chat: {line}");
//!         }
//!         if ctx.is_dead() {
//!             ctx.respawn();
//!         }
//!     }
//! }
//!
//! # async fn run() -> Result<(), Box<dyn std::error::Error>> {
//! let client = Client::new("localhost:25565".parse()?, GameVersion::V1_8_9, Account::offline("Steve")?);
//! let end = client.run(&mut Echo).await?;
//! println!("session ended: {end:?}");
//! # Ok(())
//! # }
//! ```
