Struct rustc_mir::borrow_check::constraints::graph::Reverse[−][src]

pub(crate) struct Reverse;
Expand description

In reverse mode, a R1: R2 constraint results in an edge R2 -> R1. We use this for optimizing liveness computation, because then we wish to iterate from a region (e.g., R2) to all the regions that will outlive it (e.g., R1).
