Struct rustc_data_structures::obligation_forest::Outcome

pub struct Outcome<O, E> {
    pub errors: Vec<Error<O, E>>,
    pub stalled: bool,
}

Fields

errors: Vec<Error<O, E>>

Backtrace of obligations that were found to be in error.

stalled: bool

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 Error or Unchanged, those results do not affect environmental inference state. (Note that if we invoke process_obligations with no pending obligations, stalled will be true.)

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.
