Struct rustc_trait_selection::traits::FulfillmentError

pub struct FulfillmentError<'tcx> {
    pub obligation: Obligation<'tcx, Predicate<'tcx>>,
    pub code: FulfillmentErrorCode<'tcx>,
    pub points_at_arg_span: bool,
    pub root_obligation: Obligation<'tcx, Predicate<'tcx>>,
}

Fields

obligation: Obligation<'tcx, Predicate<'tcx>>

code: FulfillmentErrorCode<'tcx>

points_at_arg_span: bool

Diagnostics only: we opportunistically change the code.span when we encounter an obligation error caused by a call argument. When this is the case, we also signal that in this field to ensure accuracy of suggestions.

root_obligation: Obligation<'tcx, Predicate<'tcx>>

Diagnostics only: the ‘root’ obligation which resulted in the failure to process obligation. This is the obligation that was initially passed to register_predicate_obligation

Layout

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