Enum miri::borrow_tracker::tree_borrows::diagnostics::TransitionError

pub(super) enum TransitionError {
    ChildAccessForbidden(Permission),
    ProtectedDisabled(Permission),
    ProtectedDealloc,
}

Variants

ChildAccessForbidden(Permission)

This access is not allowed because some parent tag has insufficient permissions. For example, if a tag is Frozen and encounters a child write this will produce a ChildAccessForbidden(Frozen). This kind of error can only occur on child accesses.

ProtectedDisabled(Permission)

A protector was triggered due to an invalid transition that loses too much permissions. For example, if a protected tag goes from Active to Disabled due to a foreign write this will produce a ProtectedDisabled(Active). This kind of error can only occur on foreign accesses.

ProtectedDealloc

Cannot deallocate because some tag in the allocation is strongly protected. This kind of error can only occur on deallocations.
