Crate brane_drv

The brane-drv crate implements the ‘user delegate’ in the central compute node. To be more precise, it takes user workflows and runs them, scheduling and orchestrating external function calls (tasks) where necessary.

Modules

• check
  Implements helper functions for the check-request.
• errors
  Contains errors used within the brane-drv package only.
• gc
  Implements a small function that can be used as a “garbage collector” for brane-drv sessions.
• handler
  Implements the command handler from the client.
• planner
  Implements a planner for the instance use-case.
• spec
  Defines (public) interfaces and structs for the brane-drv crate.
• vm
  The InstanceVm provides the brane-exe plugin for communicating with an external planner and an external worker. Moreover, the client (i.e., the submitter of the workflow) is remote as well, complicating the stdout() function.
