This keeps track of whether local variables are free-ed when the function
exits even without a StorageDead
, which appears to be the case for
constants.
I'm not sure this is the right approach - @eddyb could you try and figure this out?

This field keeps track of when borrow errors are reported in the access_place function
so that there is no duplicate reporting. This field cannot also be used for the conflicting
borrow errors that is handled by the reservation_error_reported
field as the inclusion
of the Span
type (while required to mute some errors) stops the muting of the reservation
errors.

This field keeps track of when borrow conflict errors are reported for reservations, so that we don't report seemingly duplicate errors for corresponding activations
FIXME: Ideally this would be a set of BorrowIndex, not Places, but it is currently inconvenient to track down the BorrowIndex at the time we detect and report a reservation error.

Invokes access_place
as appropriate for dropping the value
at drop_place
. Note that the actual Drop
in the MIR is
always for a variable (e.g., Drop(x)
) -- but we recursively
break this variable down into subpaths (e.g., Drop(x.foo)
)
to indicate more precisely which fields might actually be
accessed by a destructor.

Currently MoveData does not store entries for all places in the input MIR. For example it will currently filter out places that are Copy; thus we do not track places of shared reference type. This routine will walk up a place along its prefixes, searching for a foundational place that is tracked in the MoveData.
An Err result includes a tag indicated why the search failed. Currently this can only occur if the place is built off of a static variable, as we do not track those in the MoveData.

If this is a field projection, and the field is being projected from a closure type,
then returns the index of the field being projected. Note that this closure will always
be self
in the current MIR, because that is the only time we directly access the fields
of a closure type.

This function iterates over all of the in-scope borrows that
conflict with an access to a place, invoking the op
callback
for each one.
"Current borrow" here means a borrow that reaches the point in the control-flow where the access occurs.
The borrow's phase is represented by the IsActive parameter passed to the callback.
