Function
DexFutureCallback
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().
