Module type Caqti1_sigs.TUPLESource

Tuple decoding functions.

These functions extracts and decodes components from a returned tuple. The first argument is the index, starting from 0. The conversion performed are the inverse of the same named functions of PARAM, so the documentation is not repeated here.

Note! Calls to these functions are only valid during a callback from one of the query execution functions. Returning a partial call or embedding the call in a returned monad leads to undefined behaviour.

Sourcetype t

An abstract type for a tuple passed by a backend to callbacks during query execution.
