data WithCursor cursorKey wrapped Source #

A wrapper for API responses which have "next_cursor" field.

The first type parameter of WithCursor specifies the field name of contents.

>>> let Just res = decode "{\"previous_cursor\": 0, \"next_cursor\": 1234567890, \"ids\": [1111111111]}" :: Maybe (WithCursor IdsCursorKey UserId)
>>> nextCursor res
1234567890
>>> contents res
[1111111111]

>>> let Just res = decode "{\"previous_cursor\": 0, \"next_cursor\": 0, \"users\": [1000]}" :: Maybe (WithCursor UsersCursorKey UserId)
>>> nextCursor res
0
>>> contents res
[1000]
