Enum rustc_trait_selection::traits::TraitQueryMode[−][src]

pub enum TraitQueryMode {
    Standard,
    Canonical,
}
Expand description

The mode that trait queries run in.

Variants

Standard
Expand description

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

Canonical
Expand description

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