Struct rustc_trait_selection::infer::outlives::verify::VerifyBoundCx

pub struct VerifyBoundCx<'cx, 'tcx> {
    tcx: TyCtxt<'tcx>,
    region_bound_pairs: &'cx IndexSet<OutlivesPredicate<GenericKind<'tcx>, Region<'tcx>>, BuildHasherDefault<FxHasher>>,
    implicit_region_bound: Option<Region<'tcx>>,
    param_env: ParamEnv<'tcx>,
}

The TypeOutlives struct has the job of “lowering” a T: 'a obligation into a series of 'a: 'b constraints and “verifys”, as described on the module comment. The final constraints are emitted via a “delegate” of type D – this is usually the infcx, which accrues them into the region_obligations code, but for NLL we use something else.

Fields

tcx: TyCtxt<'tcx>

region_bound_pairs: &'cx IndexSet<OutlivesPredicate<GenericKind<'tcx>, Region<'tcx>>, BuildHasherDefault<FxHasher>>

implicit_region_bound: Option<Region<'tcx>>

param_env: ParamEnv<'tcx>

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
