  3. lookup :: BinList a -> Int -> Maybe a

    binary-list Data.BinaryList

    O(log n). Lookup an element in the list by its index (starting from 0). If the index is out of range, Nothing is returned.

  4. lookup :: ByteString -> Trie a -> Maybe a

    bytestring-trie Data.Trie

    Return the value associated with a query string if it exists.

  5. lookup :: (IsUnit ipkg, IsUnit srcpkg) => GenericInstallPlan ipkg srcpkg -> UnitId -> Maybe (GenericPlanPackage ipkg srcpkg)

    cabal-install Distribution.Client.InstallPlan

    Lookup a package in the plan.

  6. lookup :: Ord p => p -> LexTree p a -> Maybe a

  7. lookup :: Eq a => a -> [(a, b)] -> Maybe b

    clash-prelude Clash.HaskellPrelude

    lookup key assocs looks up a key in an association list. For the result to be Nothing, the list must be finite.

    Examples

    >>> lookup 2 []
Nothing

    >>> lookup 2 [(1, "first")]
Nothing

    >>> lookup 2 [(1, "first"), (2, "second"), (3, "third")]
Just "second"

  8. lookup :: Ord k => k -> CompactMap k v -> Maybe v

    compactmap Data.CompactMap

    No documentation available.

  9. lookup :: forall (vec :: Type -> Type) v k . (Vector vec v, Ord k) => k -> CompactMap vec k v -> Maybe v

    compactmap Data.CompactMap.Generic

    No documentation available.

  10. lookup :: FromField a => NamedRecord -> ByteString -> Parser a

    csv-conduit Data.CSV.Conduit.Conversion

    Retrieve a field in the given record by name. The result is empty if the field is missing or if the value cannot be converted to the desired type.
