Enum edn::query::PatternValuePlace

[+] Show type declaration

pub enum PatternValuePlace {
    Placeholder,
    Variable(Variable),
    EntidOrInteger(i64),
    IdentOrKeyword(ValueRc<Keyword>),
    Constant(NonIntegerConstant),
}

[−] Expand description

The v part of a pattern can be much broader: it can represent integers that aren't entity IDs (particularly negative integers), strings, and all the rest. We group those under Constant.
