我们需要声明几个结构体来存储游戏的资源信息，之后我们需要将json文件解析成这几个结构体，所以我们需要添加serde依赖。
serde = { version = "1.0", features = ["derive"] }
资源相关asset.rs
use serde::Deserialize;
use std::collections::HashMap;
#[derive(Deserialize)]
pub struct AssetIndex {
pub id: String,
pub sha1: String,
pub size: u32,
#[serde(alias = "totalSize")]
pub total_size: u32,
pub url: String,
}
#[derive(Deserialize)]
pub struct Index {
pub objects: HashMap<String, Object>,
}
#[derive(Deserialize)]
pub struct Object {
pub hash: String,
pub size: u32,
}
游戏本体version.rs
use serde::Deserialize;
use crate::{asset::AssetIndex, library::Library};
pub type Libraries = Vec<Library>;
#[derive(Deserialize)]
pub struct Version {
#[serde(alias = "assetIndex")]
pub asset_index: AssetIndex,
pub downloads: Download,
pub id: String,
pub libraries: Libraries,
#[serde(alias = "mainClass")]
pub main_class: String,
#[serde(alias = "releaseTime")]
pub release_time: String,
pub time: String,
#[serde(alias = "type")]
pub type_: String,
}
#[derive(Deserialize)]
pub struct Download {
pub client: Client,
}
#[derive(Deserialize)]
pub struct Client {
pub sha1: String,
pub size: u32,
pub url: String,
}
游戏依赖库library.rs
use serde::Deserialize;
#[derive(Deserialize)]
pub struct Library {
pub downloads: Download,
pub name: String,
pub rules: Option<Vec<Rule>>,
}
#[derive(Deserialize)]
pub struct Rule {
pub action: String,
pub os: Os,
}
#[derive(Deserialize)]
pub struct Os {
pub name: String,
}
#[derive(Deserialize)]
pub struct Download {
pub artifact: Artifact,
}
#[derive(Deserialize)]
pub struct Artifact {
pub path: String,
pub sha1: String,
pub size: i32,
pub url: String,
}
还有版本清单version_manifest.rs
use serde::Deserialize;
#[derive(Deserialize)]
pub struct VersionManifest {
pub latest: Latest,
pub versions: Vec<Version>,
}
#[derive(Deserialize)]
pub struct Latest {
pub release: String,
pub snapshot: String,
}
#[derive(Deserialize)]
pub struct Version {
pub id: String,
#[serde(alias = "type")]
pub type_: String,
pub url: String,
pub time: String,
#[serde(alias = "releaseTime")]
pub release_time: String,
}
最后我们把这几个模块导入到lib.rs中。
pub mod asset;
pub mod library;
pub mod version;
pub mod version_manifest;
