Struct LightyVersionBuilder 

pub struct LightyVersionBuilder {
    pub name: String,
    pub server_url: String,
    pub minecraft_version: Option<String>,
    pub loader: Option<Loader>,
    pub game_dirs: PathBuf,
    pub java_dirs: PathBuf,
    pub mod_requests: Vec<ModRequest>,
}

Builder for LightyUpdater-managed instances.

Unlike super::VersionBuilder, loader_version here holds the LightyUpdater server URL: the actual loader and Minecraft version are fetched from that server at install time. Default paths come from the global AppState (call AppState::init first).

User-attached Modrinth / CurseForge mods can be layered on top of the server-pushed metadata via with_mod. Modpacks are intentionally not supported here — LightyUpdater is itself the modpack source of truth, mixing in a second modpack would conflict on the loader / Minecraft version.

Fields

name: String

server_url: String

minecraft_version: Option<String>

loader: Option<Loader>

game_dirs: PathBuf

java_dirs: PathBuf

mod_requests: Vec<ModRequest>

Implementations

impl LightyVersionBuilder

pub fn new(name: &str, server_url: &str) -> Self

Creates a new LightyVersionBuilder.

server_url is the LightyUpdater server endpoint; the loader and Minecraft version are resolved from its response at install time. Panics if AppState::init hasn’t been called.

Example

use lighty_core::AppState;
use lighty_version::LightyVersionBuilder;

AppState::init("MyLauncher").unwrap();
let builder = LightyVersionBuilder::new("my-server", "https://updater.example.com");

pub fn with_mod(self) -> LightyModSourcesBuilder

Opens the user-mods sub-builder. Modpacks are not exposed on purpose — see the struct doc.

Example

let builder = LightyVersionBuilder::new("server", "https://updater.example.com")
    .with_mod()
        .done();
