Enum ConstructorInput

pub enum ConstructorInput {
    ArraySyntax(Vec<Expression>),
    MapSyntax(HashMap<String, Expression>),
}

Defines the input to a constructor application.

Basically defines the arguments to a constructor application, e.g.:

// Array syntax
has-voted(Amy, Bob).

// Map syntax
has-voted(citizen1=Amy, citizen2=Bob).

Variants

ArraySyntax(Vec<Expression>)

It’s given as an array of values that must match the input to the instance completely.

MapSyntax(HashMap<String, Expression>)

It’s given as a map of field names to values that only needs to match the instance partially.
