ExtractedAttribute

velesdb_memory::extract

Struct ExtractedAttribute 

Source 
pub struct ExtractedAttribute {
    pub entity: String,
    pub key: String,
    pub value: Value,
}
Expand description

One extracted entity attribute: entity.key = value.

Attributes are what make “Theo Durand is 15” answerable by a filter rather than a similarity search: the pair is merged into the entity hub’s ColumnStore metadata, so recall_where can select on age >= 15.

value deliberately keeps its JSON type. recall_where comparisons are TYPE-STRICT with no coercion, so an age extracted as the string "15" would silently never match a numeric filter — the extraction contract therefore demands numbers stay numbers.

Fields§

§entity: String

Canonical lowercase entity the attribute belongs to.

§key: String

Attribute name, used verbatim as the metadata (ColumnStore) field.

§value: Value

Attribute value, type preserved (a number stays a JSON number).

Source§

fn quirk(&self, value: Quirk) -> Painted<&T>
