Function api 

pub fn api(opts: Opts) -> Result<CmdRes>

Input api 统一接口

Rust

 fn main() -> e_utils::Result<()> {
   if e_app::input::Opts::check_empty() {
     let _ = app::MyApp::launch()?;
   } else {
     let opts = e_app::input::Opts::new(None as Option<Vec<String>>)?;
     let res = e_app::input::api(opts)?;
     println!("{}", res.to_str()?);
   }
   Ok(())
 }
