Enum rustc_trait_selection::traits::TraitQueryMode

pub enum TraitQueryMode {
    Standard,
    Canonical,
}

The mode that trait queries run in.

Variants

Standard

Standard/un-canonicalized queries get accurate spans etc. passed in and hence can do reasonable error reporting on their own.

Canonical

Canonicalized queries get dummy spans and hence must generally propagate errors to pre-canonicalization callsites.
