1. selectFirst :: forall (m :: Type -> Type) record . (PersistQueryRead backend, MonadIO m, PersistRecordBackend record backend) => [Filter record] -> [SelectOpt record] -> ReaderT backend m (Maybe (Entity record))

   esqueleto	Database.Esqueleto.Legacy

   Get just the first record for the criterion.

2. ascNullsFirst :: PersistField a => SqlExpr (Value a) -> SqlExpr OrderBy

   esqueleto	Database.Esqueleto.PostgreSQL

   Ascending order of this field or SqlExpression with nulls coming first.

3. descNullsFirst :: PersistField a => SqlExpr (Value a) -> SqlExpr OrderBy

   esqueleto	Database.Esqueleto.PostgreSQL

   Descending order of this field or SqlExpression with nulls coming first. Note that this is the same as normal ascending ordering in Postgres, but it has been included for completeness.

4. holdFirst :: forall a (m :: Type -> Type) . (Data a, Monad m) => Cell m a a

   essence-of-live-coding	LiveCoding.Cell.Util

   Hold the first value and output it indefinitely.

5. CompactGetFirstBlockOp :: PrimOp

   ghc-lib-parser	GHC.Builtin.PrimOps

   No documentation available.

6. replaceFirstNode :: forall n (x :: Extensibility) . Block n C x -> n C O -> Block n C x

   ghc-lib-parser	GHC.Cmm.Dataflow.Block

   No documentation available.

7. toBlockListEntryFirst :: CmmGraph -> [CmmBlock]

   ghc-lib-parser	GHC.Cmm.Utils

   like toBlockList, but the entry block always comes first

8. toBlockListEntryFirstFalseFallthrough :: CmmGraph -> [CmmBlock]

   ghc-lib-parser	GHC.Cmm.Utils

   Like toBlockListEntryFirst, but we strive to ensure that we order blocks so that the false case of a conditional jumps to the next block in the output list of blocks. This matches the way OldCmm blocks were output since in OldCmm the false case was a fallthrough, whereas in Cmm conditional branches have both true and false successors. Block ordering can make a big difference in performance in the LLVM backend. Note that we rely crucially on the order of successors returned for CmmCondBranch by the NonLocal instance for CmmNode defined in GHC.Cmm.Node. -GBM

9. getFirstAnnotations :: Typeable a => ([Word8] -> a) -> ModGuts -> CoreM (ModuleEnv a, NameEnv a)

   ghc-lib-parser	GHC.Core.Opt.Monad

   Get at most one annotation of a given type per annotatable item.

10. contramapFirstWhenMatched :: forall b a (f :: Type -> Type) y z . (b -> a) -> WhenMatched f a y z -> WhenMatched f b y z

    ghc-lib-parser	GHC.Data.Word64Map.Internal

    Map contravariantly over a WhenMatched f _ y z.
