Enum rustc_infer::traits::ScrubbedTraitError

source ·

pub enum ScrubbedTraitError<'tcx> {
    TrueError,
    Ambiguity,
    Cycle(Vec<PredicateObligation<'tcx>>),
}

Expand description

A trait error with most of its information removed. This is the error returned by an ObligationCtxt by default, and suitable if you just want to see if a predicate holds, and don’t particularly care about the error itself (except for if it’s an ambiguity or true error).

use ObligationCtxt::new_with_diagnostics to get a FulfillmentError.

Variants§

§

TrueError

A real error. This goal definitely does not hold.

§

Ambiguity

An ambiguity. This goal may hold if further inference is done.

§

Cycle(Vec<PredicateObligation<'tcx>>)

An old-solver-style cycle error, which will fatal.
