Expand description

This struct brings together a constraint set and a (normal, not reverse) constraint graph. It implements the graph traits and is usd for doing the SCC computation.

Fields

set: &'s OutlivesConstraintSet<'tcx>constraint_graph: &'s ConstraintGraph<D>static_region: RegionVid

Implementations

Creates a “dependency graph” where each region constraint R1: R2 is treated as an edge R1 -> R2. We use this graph to construct SCCs for region inference but also for error reporting.

Given a region R, iterate over all regions R1 such that there exists a constraint R: R1.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
