Struct conch_runtime::env::EnvConfig

pub struct EnvConfig<A, IO, FD, L, V, EX, WD, N, ERR> {
    pub interactive: bool,
    pub args_env: A,
    pub async_io_env: IO,
    pub file_desc_env: FD,
    pub last_status_env: L,
    pub var_env: V,
    pub exec_env: EX,
    pub working_dir_env: WD,
    pub fn_name: PhantomData<N>,
    pub fn_error: PhantomData<ERR>,
}

A struct for configuring a new Env instance.

It implements Default (via DefaultEnvConfig alias) so it is possible to selectively override certain environment modules while retaining the rest of the default implementations.

let lp = tokio_core::reactor::Core::new().unwrap();
let env = Env::with_config(EnvConfig {
    args_env: ArgsEnv::with_name(Rc::new(String::from("my_shell"))),
    .. DefaultEnvConfig::new(lp.remote(), None).expect("failed to create config")
});

assert_eq!(**env.name(), "my_shell");
