Expand description
Things that can be visited by a ResultsVisitor
.
This trait exists so that we can visit the results of multiple dataflow analyses simultaneously.
DO NOT IMPLEMENT MANUALLY. Instead, use the impl_visitable
macro below.

Required Methods§
sourcefn new_flow_state(&self, body: &Body<'tcx>) -> Self::FlowState
fn new_flow_state(&self, body: &Body<'tcx>) -> Self::FlowState
Creates an empty FlowState
to hold the transient state for these dataflow results.
The value of the newly created FlowState
will be overwritten by reset_to_block_entry
before it can be observed by a ResultsVisitor
.
