Enum tantivy::schema::Cardinality

pub enum Cardinality {
    SingleValue,
    MultiValues,
}

Express whether a field is single-value or multi-valued.

Variants

SingleValue

The document must have exactly one value associated to the document.

MultiValues

The document can have any number of values associated to the document. This is more memory and CPU expensive than the SingleValue solution.
