Enum fungi_lang::dynamics::ExpTerm

pub enum ExpTerm {
    Lam(EnvRec, Var, Rc<Exp>),
    HostFn(HostEvalFn, Vec<RtVal>),
    Ret(RtVal),
}

Terminal expressions (a la CBPV), but in environment-passing style, where (closed) lambda terms have closing environments.

Variants

Lam(EnvRec, Var, Rc<Exp>)

Lambda expression, with a closing environment

HostFn(HostEvalFn, Vec<RtVal>)

Rust-level lambda function, with Fungi-level argument values

Ret(RtVal)

Produce the given run-time value
