pub struct Env<'a> {
    pub inner: &'a mut Env,
    pub last_command_subst_exit_status: Option<ExitStatus>,
    pub will_split: bool,
}

This sturct extends yash_env::Env with some properties.

Fields

inner: &'a mut Env

Main part of the environment

Whether the expansion result will be subjected to field splitting.

This flag will affect the expansion of the $* special parameter.
