lookup :: Text -> OrderedMap v -> Maybe vgraphql Language.GraphQL.Execute.OrderedMap Looks up a value in this map by key.
lookup :: KeySpec -> KVITable v -> Maybe vkvitable Data.KVITable Retrieve an entry from the KVITable given a keyspec. The keyspec may be minimally specified (i.e. it does not need to contain keys whose value is the default key value) and it may present the keys out of order and the lookup will still succeed (if there is a value for the normalized keyspec), but it will be faster to use the normalized key directly. The performance of lookup degrades exponentially on a sparse KVITable: an unset KVITable entry is indistinguishable from a non-normalized keyspec, so if the initial query fails, the keyspec is normalized and then the lookup is re-attempted. This may be fine for an individual query, but for large numbers of queries this is excessively slow. To mitigate this, the lookup' can be used, which assumes the use of a normalized key.
lookup :: Ord key => key -> LRU key val -> (LRU key val, Maybe val)lrucache Data.Cache.LRU Look up an item in an LRU. If it was present, it is marked as the most recently accesed in the returned LRU.
lookup :: Ord key => key -> AtomicLRU key val -> IO (Maybe val)lrucache Data.Cache.LRU.IO Look up a key in an AtomicLRU. See lookup for the semantics.
lookup :: Ord key => key -> AtomicLRU key val -> IO (Maybe val)lrucache Data.Cache.LRU.IO.Internal Look up a key in an AtomicLRU. See lookup for the semantics.
lookup :: Ord key => key -> LRU key val -> (LRU key val, Maybe val)lrucache Data.Cache.LRU.Internal Look up an item in an LRU. If it was present, it is marked as the most recently accesed in the returned LRU.
lookup :: Ord k => k -> Map k v -> Maybe vmonoidmap-internal Data.MonoidMap.Internal.RecoveredMap No documentation available.
lookup :: Ord k => k -> LRUCache k v -> Maybe vnetwork-control Network.Control Looking up. O(log n)
lookup :: Name -> Filter -> Maybe FilterFunctionpandoc-lua-marshal Text.Pandoc.Lua.Marshal.Filter Looks up a filter function in a Lua Filter.
lookup :: Int -> By6Bits e -> Maybe eprimitive-extras PrimitiveExtras.By6Bits Lookup an item at the index.
