Exact lookup

1. lookup :: (Eq k, Hashable k) => HashTable s k v -> k -> ST s (Maybe v)

   hashtables	Data.HashTable.ST.Basic

   See the documentation for this function in lookup.

2. lookup :: (Eq k, Hashable k) => HashTable s k v -> k -> ST s (Maybe v)

   hashtables	Data.HashTable.ST.Cuckoo

   See the documentation for this function in lookup.

3. lookup :: (Eq k, Hashable k) => HashTable s k v -> k -> ST s (Maybe v)

   hashtables	Data.HashTable.ST.Linear

   See the documentation for this function in Data.HashTable.Class#v:lookup.

4. lookup :: TarIndex -> FilePath -> Maybe TarIndexEntry

   tar	Codec.Archive.Tar.Index

   Look up a given filepath in the TarIndex. It may return a TarFileEntry containing the TarEntryOffset of the file within the tar file, or if the filepath identifies a directory then it returns a TarDir containing the list of files within that directory. Given the TarEntryOffset you can then use one of the I/O operations:

   • hReadEntry to read the whole entry;
   • hReadEntryHeader to read just the file metadata (e.g. its length);

5. lookup :: Key a -> Vault -> Maybe a

   vault	Data.Vault.Lazy

   Lookup the value of a key in the vault.

6. lookup :: Key s a -> Vault s -> Maybe a

   vault	Data.Vault.ST.Lazy

   Lookup the value of a key in the vault.

7. lookup :: Key s a -> Vault s -> Maybe a

   vault	Data.Vault.ST.Strict

   Lookup the value of a key in the vault.

8. lookup :: Key a -> Vault -> Maybe a

   vault	Data.Vault.Strict

   Lookup the value of a key in the vault.

9. lookup :: IsNode a => Key a -> Graph a -> Maybe a

   Cabal-syntax	Distribution.Compat.Graph

   O(log V). Lookup the node at a key in the graph.

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

    Cabal-syntax	Distribution.Compat.Prelude

    No documentation available.
