quotes are supported), +with the exception of `COUNT` and the special `-` form of `PATH`. + +Directives are assertions that place constraints on the generated HTML. + +All directives (except `files`)

Constructing a `ParamEnv` looks at all of the trait bounds in the env and explicitly adds new where clauses to the `ParamEnv` for any supertraits found on the traits. + +A concrete example would be the following function: +```rust +trait Trait: SuperTrait {} +trait SuperTrait: SuperSuperTrait {} + +// `bar`'s unelaborated `ParamEnv` would be: +// `[T: Sized, T: Copy, T: Trait]` +fn bar<T: Copy + Trait>(a: T) { + requires_impl(a); +} + +fn requires_impl<T: Clone + SuperSuperTrait>(a: T) {} +``` + +If we did not elaborate the env then the `requires_impl` call would fail to typecheck as we would not be able to prove `T: Clone` or `T: SuperSuperTrait`. In practice we elaborate the env which means that `bar`'s `ParamEnv` is actually: +`[T: Sized, T: Copy, T: Clone, T: Trait, T: SuperTrait, T: SuperSuperTrait]` +This allows us to prove `T: Clone` and `T: SuperSuperTrait` when type checking `bar`. + +The `Clone` trait has a `Sized` supertrait however we do not end up with two `T: Sized` bounds in the env (one for the supertrait and one for the implicitly added `T: Sized` bound) as the elaboration process (implemented via [`util::elaborate`][elaborate]) deduplicates where clauses. + +A side effect of this is that even if no actual elaboration of supertraits takes place, the existing where clauses in the env are _also_ deduplicated. See the following example: +```rust +trait Trait {} +// The unelaborated `ParamEnv` would be: +// `[T: Sized, T: Trait, T: Trait]` +// but after elaboration it would be: +// `[T: Sized, T: Trait]` +fn foo<T: Trait + Trait>() {} +``` + +The [next-gen trait solver][next-gen-solver] also requires this elaboration to take place. + +[elaborate]: https://doc.rust-lang.org/nightly/nightly-rustc/rustc_infer/traits/util/fn.elaborate.html +[next-gen-solver]: ./solve/trait-solving.md + +#### Normalizing all bounds + +In the old trait solver the where clauses stored in `ParamEnv` are required to be fully normalized as otherwise the trait solver will not function correctly. A concrete example of needing to normalize the `ParamEnv` is the following: +```rust +trait Trait<T> { + type Assoc; +} + +trait Other { + type Bar; +} + +impl<T> Other for T { + type Bar = u32; +} + +// `foo`'s unnormalized `ParamEnv` would be: +// `[T: Sized, U: Sized, U: Trait<T::Bar>]` +fn foo<T, U>(a: U) +where + U: Trait<<T as Other>::Bar>, +{ + requires_impl(a); +} + +fn requires_impl<U: Trait<u32>>(_: U) {} +``` + +As humans we can tell that `<T as Other>::Bar` is equal to `u32` so the trait bound on `U` is equivalent to `U: Trait<u32>`. In practice trying to prove `U: Trait<u32>` in the old solver in this environment would fail as it is unable to determine that `<T as Other>::Bar` is equal to `u32`. + +To work around this we normalize `ParamEnv`'s after constructing them so that `foo`'s `ParamEnv` is actually: `[T: Sized, U: Sized, U: Trait<u32>]` which means the trait solver is now able to use the `U: Trait<u32>` in the `ParamEnv` to determine that the trait bound `U: Trait<u32>` holds. + +This workaround does not work in all cases as normalizing associated types requires a `ParamEnv` which introduces a bootstrapping problem. We need a normalized `ParamEnv` in order for normalization to give correct results, but we need to normalize to get that `ParamEnv`. Currently we normalize the `ParamEnv` once using the unnormalized param env and it tends to give okay results in practice even though there are some examples where this breaks ([example]). + +In the next-gen trait solver the requirement for all where clauses in the `ParamEnv` to be fully normalized is not present and so we do not normalize when constructing `ParamEnv`s. + +[example]: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=e6933265ea3e84eaa47019465739992c +[pe]: https://doc.rust-lang.org/nightly/nightly-rustc/rustc_middle/ty/struct.ParamEnv.html +[normalize_env_or_error]: https://doc.rust-lang.org/nightly/nightly-rustc/rustc_trait_selection/traits/fn.normalize_param_env_or_error.html + +## Typing Modes + +Depending on what context we are performing type system operations in, different behaviour may be required.

Instead of requiring - backends to implement both the intrinsic and the MIR operation, the `lower_intrinsics` pass - will convert the calls to the MIR operation. Backends do not need to know about these intrinsics - at all. These intrinsics only make sense without a body, and can either be declared as a "rust-intrinsic" - or as a `#[rustc_intrinsic]`.
