Allow(&'a Lock<TaskDeps>)
New dependencies can be added to the
TaskDeps. This is used when executing a ‘normal’ query
(no eval_always modifier)
EvalAlways
This is used when executing an eval_always query. We don’t
need to track dependencies for a query that’s always
re-executed – but we need to know that this is an eval_always
query in order to emit dependencies to DepNodeIndex::FOREVER_RED_NODE
when directly feeding other queries.
Ignore
New dependencies are ignored. This is also used for dep_graph.with_ignore.
Forbid
Any attempt to add new dependencies will cause a panic. This is used when decoding a query result from disk, to ensure that the decoding process doesn’t itself require the execution of any queries.
