Writer interface
data WriterHandle (f :: Type -> Type) Source #
Arguments
| :: Foldable f | |
| => f String | index names: a fixed-length collection of the names of indices for this stream. Use Proxy if you don't want any indices. If you want only one type of index, use `Identity ""`. |
| -> FilePath | |
| -> IO (WriterHandle f) |
closeWriter :: Foldable f => WriterHandle f -> IO () Source #
Flush any pending data and close a WriterHandle.
withWriter :: Foldable f => f String -> FilePath -> (WriterHandle f -> IO a) -> IO a Source #
flush :: WriterHandle f -> IO () Source #
Flush the changes.
getLastSeqNo :: WriterHandle f -> IO Int Source #
Get the sequential number of the last item item written.
