pub struct Outcome<O, E> { pub completed: Vec<O>, pub errors: Vec<Error<O, E>>, pub stalled: bool, }
🔬 This is a nightly-only experimental API. (
rustc_private
)Fields
completed: Vec<O>
🔬 This is a nightly-only experimental API. (
rustc_private
)Obligations that were completely evaluated, including all (transitive) subobligations.
errors: Vec<Error<O, E>>
🔬 This is a nightly-only experimental API. (
rustc_private
)Backtrace of obligations that were found to be in error.
stalled: bool
🔬 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.)
