Struct MetadataMatcher 

pub struct MetadataMatcher {
    pub fields: HashMap<String, MetadataPredicate>,
    pub not: Option<Box<MetadataMatcher>>,
}

Metadata matcher: map of field -> predicate, with an optional not sub-matcher (negation). The not: key is reserved and parsed specially — it cannot be used as a metadata field name.

Fields
