§machine: MStores the Machine instance.
Note: the stack is provided by the machine.
tcx: TyCtxtAt<'tcx>The results of the type checker, from rustc. The span in this is the “root” of the evaluation, i.e., the const we are evaluating (if this is CTFE).
param_env: ParamEnv<'tcx>§memory: Memory<'mir, 'tcx, M>The virtual memory system.
recursion_limit: LimitThe recursion limit (cached from tcx.recursion_limit(()))

fn truncate_to_ptr(&self, _: (u64, bool)) -> (u64, bool)
Helper function: truncate given value-“overflowed flag” pair to pointer size and
update “overflowed flag” if there was an overflow.
This should be called by all the other methods before returning!

Layout§
Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
