Fields

🔬 This is a nightly-only experimental API. (rustc_private)

Obligations that were completely evaluated, including all (transitive) subobligations.

Backtrace of obligations that were found to be in error.

🔬 This is a nightly-only experimental API. (rustc_private)

If true, then we saw no successful obligations, which means there is no point in further iteration. This is based on the assumption that when trait matching returns Err or Ok(None), those results do not affect environmental inference state. (Note that if we invoke process_obligations with no pending obligations, stalled will be true.)
