Module rustc_const_eval::interpret::machine

This module contains everything needed to instantiate an interpreter. This separation exists to ensure that no fancy miri features like interpreting common C functions leak into CTFE.

Macros

• compile_time_machine
  A lot of the flexibility above is just needed for Miri, but all “compile-time” machines (CTFE and ConstProp) use the same instance. Here, we share that code.

Enums

• ReturnAction
  Data returned by Machine::after_stack_pop, and consumed by InterpCx::return_from_current_stack_frame to determine what actions should be done when returning from a stack frame.

Traits

• AllocMap
  The functionality needed by memory to manage its allocations
• Machine
  Methods of this trait signifies a point where CTFE evaluation would fail and some use case dependent behaviour can instead be applied.
• MayLeak
  Whether this kind of memory is allowed to leak
