Enum rustc_borrowck::LocalMutationIsAllowed

source · [−]

pub(crate) 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`

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

`No`
