Enum rustc_mir::borrow_check::LocalMutationIsAllowed[−][src]

enum LocalMutationIsAllowed {
    Yes,
    ExceptUpvars,
    No,
}
Expand description

When checking permissions for a place access, this flag is used to indicate that an immutable local place can be mutated.

Variants

Yes
ExceptUpvars
Expand description

We want use of immutable upvars to cause a “write to immutable upvar” error, not an “reassignment” error.

No
