14.4.34  Io_Bound_Task_Hostthreads

The standard library Io_Bound_Task_Hostthreads api defines access to hostthreads which offload I/O-intensive computations from the main threadkit hostthread (or, more generally, any slow operations which are not CPU-bound).

The Io_Bound_Task_Hostthreads api is implemented by the io_bound_task_hostthreads package.

The Io_Bound_Task_Hostthreads api source code is in src/lib/std/src/hostthread/io-bound-task-hostthreads.api.
