使用eframe框架可以很方便的创建native应用或者是web应用;
可以参照模板 eframe_template ;
拉取代码后可以直接指令 cargo run 编译运行,如下;
hint
#[cfg(not(target_arch = "wasm32"))]
fn main() -> eframe::Result<()> {
// Log to stdout (if you run with `RUST_LOG=debug`).
tracing_subscriber::fmt::init();
let native_options = eframe::NativeOptions:: default ();
eframe::run_native(
"eframe template" ,
native_options,
Box:: new (|cc| Box:: new (eframe_template::TemplateApp:: new (cc))),
)
}
// when compiling to web using trunk.
#[cfg(target_arch = "wasm32")]
fn main() {
// Make sure panics are logged using `console.error`.
console_error_panic_hook::set_once();
// Redirect tracing to console.log and friends:
tracing_wasm::set_as_global_default();
let web_options = eframe::WebOptions:: default ();
wasm_bindgen_futures::spawn_local(async {
eframe::start_web(
"the_canvas_id" , // hardcode it
web_options,
Box:: new (|cc| Box:: new (eframe_template::TemplateApp:: new (cc))),
)
.await
.expect( "failed to start eframe" );
});
}

条件编译区分wasm32和native本机,根据编译目标不同执行不同的代码;
默认编译目标为本机平台;
执行指令 rustup target list查看所有支持的平台;
当需要编译为wasm到浏览器中运行时,需添加编译器wasm32-unknown-unknown
执行命令rustup target add wasm32-unknown-unknown 进行添加;
此时就需要 Trunk 来进行编译;
通过cargo install --locked trunk 指令来编译安装trunk工具;
执行指令trunk server 编译并执行程序http://127.0.0.1:8080 ,如下;
trunk serve --port=8899
