Struct UnionMember 

pub struct UnionMember<P: Phase = Raw> {
    pub name: Spanned<ConstructorName>,
    pub payload: Option<Vec<FieldDecl<P>>>,
    pub span: Span,
}

A member of a type declaration body: a constructor with an optional payload.

Forms:

• Unit: Coast — payload is None.
• Record-payload (parens): Impulsive(delta_v: Velocity) — payload is Some(vec![…]).
• Record-payload (braces): LowThrust { thrust: Force, duration: Time } — payload is Some(vec![…]). The brace/paren choice is purely surface syntax; both produce the same AST.

Fields

name: Spanned<ConstructorName>

The constructor’s name. Lives in the constructor namespace — distinct from the type namespace.

payload: Option<Vec<FieldDecl<P>>>

Inline payload fields, or None for unit constructors.

span: Span
