Function

DexFutureCallback

Declaration 

DexFuture*
(* DexFutureCallback) (
  DexFuture* future,
  gpointer user_data
)

Description [src]

A DexFutureCallback can be executed from a DexBlock as response to another DexFuture resolving or rejecting.

The callback will be executed within the scheduler environment the block is created within when using dex_future_then(), dex_future_catch() dex_future_finally(), dex_future_all(), and similar functions.

This is the expected way to handle completion of a future when not using DexFiber via dex_scheduler_spawn().
