The result will be number of elements returned and the list of elements with all properties except all values will be empty.

Tuple Fields

0: QueryIds

Trait Implementations

impl Clone for SelectKeysQuery

fn clone(&self) -> SelectKeysQuery

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SelectKeysQuery

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SelectKeysQuery

fn eq(&self, other: &SelectKeysQuery) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Query for &SelectKeysQuery

fn process<Store: StorageData>( &self, db: &DbImpl<Store>, ) -> Result<QueryResult, DbError>

impl Query for SelectKeysQuery

fn process<Store: StorageData>( &self, db: &DbImpl<Store>, ) -> Result<QueryResult, DbError>

impl Serialize for SelectKeysQuery

fn serialized_size(&self) -> u64
