Locoのいつの間にかの仕様変更？

なぜか最初はstatic使えなかったので、

app.rs

use std::path::Path;

use async_trait::async_trait;
use loco_rs::{
    app::{AppContext, Hooks},
    // 追加
    boot::{create_app, BootResult, StartMode},
    controller::AppRoutes,
    db::{self, truncate_table},
    // 追加
    environment::Environment,
    task::Tasks,
    worker::{AppWorker, Processor},
    Result,
};
// 追加
use migration::Migrator;
use sea_orm::DatabaseConnection;

use crate::{
    controllers,
    models::_entities::{notes, users},
    tasks,
    workers::downloader::DownloadWorker,
};

pub struct App;
#[async_trait]
impl Hooks for App {
    fn app_name() -> &'static str {
        env!("CARGO_CRATE_NAME")
    }

    // 追加
    fn app_version() -> String {
        format!(
            "{} ({})",
            env!("CARGO_PKG_VERSION"),
            option_env!("BUILD_SHA")
                .or(option_env!("GITHUB_SHA"))
                .unwrap_or("dev")
        )
    }

    // 追加
    // fn boot(mode: StartMode, environment: Environment) -> BootResult {
    async fn boot(mode: StartMode, environment: &Environment) -> Result<BootResult> {
        // create_app::<Self, Migrator>(mode, "develop").await
        create_app::<Self, Migrator>(mode, environment).await
    }

    // fn routes() -> AppRoutes {
    fn routes(_ctx: &AppContext) -> AppRoutes {
        AppRoutes::with_default_routes()
            .add_route(controllers::comment::routes())
            .add_route(controllers::articles::routes())
            .add_route(controllers::guide::routes())
            .add_route(controllers::notes::routes())
            .add_route(controllers::auth::routes())
            .add_route(controllers::user::routes())
    }

loco-rs = { version = "0.1.6" } ↓ loco-rs = { version = "0.2.3" } このバージョン違い？

この辺も

#async-trait = "0.1.0"
async-trait = "0.1.77"
