[−][src]Struct salsa::QueryTable
Return value from [the query
method] on Database
.
Gives access to various less common operations on queries.
Methods
impl<'me, DB, Q> QueryTable<'me, DB, Q> where
DB: GetQueryTable<Q>,
Q: Query<DB> + 'me,
[src]
DB: GetQueryTable<Q>,
Q: Query<DB> + 'me,
impl<DB, Q, '_> QueryTable<'_, DB, Q> where
DB: GetQueryTable<Q>,
Q: Query<DB>,
[src]
DB: GetQueryTable<Q>,
Q: Query<DB>,
pub fn get(&self, key: Q::Key) -> Q::Value
[src]
Execute the query on a given input. Usually it's easier to invoke the trait method directly. Note that for variadic queries (those with no inputs, or those with more than one input) the key will be a tuple.
pub fn sweep(&self, strategy: SweepStrategy) where
Q::Storage: QueryStorageMassOps<DB>,
[src]
Q::Storage: QueryStorageMassOps<DB>,
Remove all values for this query that have not been used in the most recent revision.

type Key = Q::Key
Key of this query.
type Value = Q::Value
Value of this query.
