Function rustc::traits::normalize_projection_type [−] [src]

pub fn normalize_projection_type<'a, 'b, 'gcx, 'tcx>(
    selcx: &'a mut SelectionContext<'b, 'gcx, 'tcx>, 
    param_env: ParamEnv<'tcx>, 
    projection_ty: ProjectionTy<'tcx>,

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

The guts of normalize: normalize a specific projection like <T as Trait>::Item. The result is always a type (and possibly additional obligations). If ambiguity arises, which implies that there are unresolved type variables in the projection, we will substitute a fresh type variable $X and generate a new obligation <T as Trait>::Item == $X for later.
