Expand description

Query result.

## Fields§

§`partition_index: usize`

Partition index.

§`vector_id: Uuid`

Vector ID. Must be unique across the entire database.

§`vector_index: usize`

Vector index. Local index in the partition.

§`squared_distance: T`

Approximate squared distance.

## Implementations§

source§

### impl<'a, T, FS> QueryResult<'a, T, FS>where T: Scalar, FS: FileSystem, Database<T, FS>: LoadPartition<T> + LoadCodebook<T> + LoadPartitionCentroids<T>,

source

#### pub fn get_attribute<K>( &self, key: &K ) -> Result<Option<AttributeValueRef<'_>>, Error>where String: Borrow<K>, K: Hash + Eq + ?Sized,

Returns an attribute value of the vector corresponding to the result.

The first call of this function on a result belonging to a partition will take longer because it will load the attributes of the partition.
