Struct Def 

pub struct Def {
    pub params: Vec<Ty>,
    pub ret: Ty,
    pub effects: BTreeSet<EffectKind>,
    pub body: Term,
    pub pre: Option<Term>,
    pub post: Option<Term>,
}

One verified unit of Weft: typed parameters, result type, declared effect row, optional contracts, and the body. Its hash is its name.

Fields

params: Vec<Ty>

ret: Ty

effects: BTreeSet<EffectKind>

Everything this definition (transitively) may construct.

body: Term

pre: Option<Term>

Contract: precondition over the parameters (must type as Bool).

post: Option<Term>

Contract: postcondition over parameters + result (result = index 0).
