Enum Sexp

pub enum Sexp<V> {
    Symbol(Cow<'static, str>),
    Compound(Vec<Sexp<V>>),
    Inlined(V),
}

S-expression.

Variants

Symbol(Cow<'static, str>)

A symbol that needs to be resolved in an environment.

Compound(Vec<Sexp<V>>)

A list, such as (+ 1 2).

Inlined(V)

An inlined value.

Pre-resolved values. Be-careful: self-referral inlined values can cause Display or Debug to stack overflow.
