Enum Pattern 

pub enum Pattern<A> {
    Wildcard(A),
    As(A, Box<Pattern<A>>, Name),
    Tuple(A, Vec<Pattern<A>>),
    Constructor(A, FQName, Vec<Pattern<A>>),
    EmptyList(A),
    HeadTail(A, Box<Pattern<A>>, Box<Pattern<A>>),
    Literal(A, Literal),
    Unit(A),
}

Pattern for pattern matching.

These are morphir-elm’s eight patterns and no more: a variable binding is an As over a wildcard, so there is no VariablePattern to read or write.

Variants

Constructor(A, FQName, Vec<Pattern<A>>)
