//! ### Inferring borrow kinds for upvars //! //! Whenever there is a closure expression, we need to determine how each //! upvar is used. We do this by initially assigning each upvar an //! immutable "borrow kind" (see `ty::BorrowKind` for details) and then //! "escalating" the kind as needed. The borrow kind proceeds according to //! the following lattice: //! //! ty::ImmBorrow -> ty::UniqueImmBorrow -> ty::MutBorrow //! //! So, for example, if we see an assignment `x = 5` to an upvar `x`, we //! will promote its borrow kind to mutable borrow. If we see an `&mut x` //! we'll do the same. Naturally, this applies not just to the upvar, but //! to everything owned by `x`, so the result is the same for something //! like `x.f = 5` and so on (presuming `x` is not a borrowed pointer to a //! struct). These adjustments are performed in //! `adjust_upvar_borrow_kind()` (you can trace backwards through the code //! from there). //! //! The fact that we are inferring borrow kinds as we go results in a //! semi-hacky interaction with mem-categorization. In particular, //! mem-categorization will query the current borrow kind as it //! categorizes, and we'll return the *current* value, but this may get //! adjusted later. Therefore, in this module, we generally ignore the //! borrow kind (and derived mutabilities) that are returned from //! mem-categorization, since they may be inaccurate. (Another option //! would be to use a unification scheme, where instead of returning a //! concrete borrow kind like `ty::ImmBorrow`, we return a //! `ty::InferBorrow(upvar_id)` or something like that, but this would //! then mean that all later passes would have to check for these figments //! and report an error, and it just seems like more mess in the end.) use super::FnCtxt; use crate::expr_use_visitor as euv; use crate::mem_categorization as mc; use crate::mem_categorization::PlaceBase; use rustc_data_structures::fx::FxIndexMap; use rustc_hir as hir; use rustc_hir::def_id::DefId; use rustc_hir::def_id::LocalDefId; use rustc_hir::intravisit::{self, NestedVisitorMap, Visitor}; use rustc_infer::infer::UpvarRegion; use rustc_middle::ty::{self, Ty, TyCtxt, UpvarSubsts}; use rustc_span::{Span, Symbol}; impl<'a, 'tcx> FnCtxt<'a, 'tcx> { pub fn closure_analyze(&self, body: &'tcx hir::Body<'tcx>) { InferBorrowKindVisitor { fcx: self }.visit_body(body); // it's our job to process these. assert!(self.deferred_call_resolutions.borrow().is_empty()); } } struct InferBorrowKindVisitor<'a, 'tcx> { fcx: &'a FnCtxt<'a, 'tcx>, } impl<'a, 'tcx> Visitor<'tcx> for InferBorrowKindVisitor<'a, 'tcx> { type Map = intravisit::ErasedMap<'tcx>; fn nested_visit_map(&mut self) -> NestedVisitorMap<Self::Map> { NestedVisitorMap::None } fn visit_expr(&mut self, expr: &'tcx hir::Expr<'tcx>) { if let hir::ExprKind::Closure(cc, _, body_id, _, _) = expr.kind { let body = self.fcx.tcx.hir().body(body_id); self.visit_body(body); self.fcx.analyze_closure(expr.hir_id, expr.span, body, cc); } intravisit::walk_expr(self, expr); } } impl<'a, 'tcx> FnCtxt<'a, 'tcx> { /// Analysis starting point. fn analyze_closure( &self, closure_hir_id: hir::HirId, span: Span, body: &hir::Body<'_>, capture_clause: hir::CaptureBy, ) { debug!("analyze_closure(id={:?}, body.id={:?})", closure_hir_id, body.id()); // Extract the type of the closure. let ty = self.node_ty(closure_hir_id); let (closure_def_id, substs) = match ty.kind { ty::Closure(def_id, substs) => (def_id, UpvarSubsts::Closure(substs)), ty::Generator(def_id, substs, _) => (def_id, UpvarSubsts::Generator(substs)), ty::Error => { // #51714: skip analysis when we have already encountered type errors return; } _ => { span_bug!( span, "type of closure expr {:?} is not a closure {:?}", closure_hir_id, ty ); } }; let infer_kind = if let UpvarSubsts::Closure(closure_substs) = substs { self.closure_kind(closure_substs).is_none().then_some(closure_substs) } else { None }; if let Some(upvars) = self.tcx.upvars(closure_def_id) { let mut upvar_list: FxIndexMap<hir::HirId, ty::UpvarId> = FxIndexMap::with_capacity_and_hasher(upvars.len(), Default::default()); for (&var_hir_id, _) in upvars.iter() { let upvar_id = ty::UpvarId { var_path: ty::UpvarPath { hir_id: var_hir_id }, closure_expr_id: closure_def_id.expect_local(), }; debug!("seed upvar_id {:?}", upvar_id); // Adding the upvar Id to the list of Upvars, which will be added // to the map for the closure at the end of the for loop. upvar_list.insert(var_hir_id, upvar_id); let capture_kind = match capture_clause { hir::CaptureBy::Value => ty::UpvarCapture::ByValue, hir::CaptureBy::Ref => { let origin = UpvarRegion(upvar_id, span); let upvar_region = self.next_region_var(origin); let upvar_borrow = ty::UpvarBorrow { kind: ty::ImmBorrow, region: upvar_region }; ty::UpvarCapture::ByRef(upvar_borrow) } }; self.tables.borrow_mut().upvar_capture_map.insert(upvar_id, capture_kind); } // Add the vector of upvars to the map keyed with the closure id. // This gives us an easier access to them without having to call // tcx.upvars again.. if !upvar_list.is_empty() { self.tables.borrow_mut().upvar_list.insert(closure_def_id, upvar_list); } } let body_owner_def_id = self.tcx.hir().body_owner_def_id(body.id()); assert_eq!(body_owner_def_id.to_def_id(), closure_def_id); let mut delegate = InferBorrowKind { fcx: self, closure_def_id, current_closure_kind: ty::ClosureKind::LATTICE_BOTTOM, current_origin: None, adjust_upvar_captures: ty::UpvarCaptureMap::default(), }; euv::ExprUseVisitor::new( &mut delegate, &self.infcx, body_owner_def_id, self.param_env, &self.tables.borrow(), ) .consume_body(body); if let Some(closure_substs) = infer_kind { // Unify the (as yet unbound) type variable in the closure // substs with the kind we inferred. let inferred_kind = delegate.current_closure_kind; let closure_kind_ty = closure_substs.as_closure().kind_ty(); self.demand_eqtype(span, inferred_kind.to_ty(self.tcx), closure_kind_ty); // If we have an origin, store it. if let Some(origin) = delegate.current_origin { self.tables.borrow_mut().closure_kind_origins_mut().insert(closure_hir_id, origin); } } self.tables.borrow_mut().upvar_capture_map.extend(delegate.adjust_upvar_captures); // Now that we've analyzed the closure, we know how each // variable is borrowed, and we know what traits the closure // implements (Fn vs FnMut etc).

The reason for this design is that the /// upvar types can reference lifetimes that are internal to the /// creating function. In my example above, for example, the lifetime /// `'b` represents the scope of the closure itself; this is some /// subset of `foo`, probably just the scope of the call to the to /// `do()`. If we just had the lifetime/type parameters from the /// enclosing function, we couldn't name this lifetime `'b`. Note that /// there can also be lifetimes in the types of the upvars themselves, /// if one of them happens to be a reference to something that the /// creating fn owns. /// /// OK, you say, so why not create a more minimal set of parameters /// that just includes the extra lifetime parameters? The answer is /// primarily that it would be hard --- we don't know at the time when /// we create the closure type what the full types of the upvars are, /// nor do we know which are borrowed and which are not. In this /// design, we can just supply a fresh type parameter and figure that /// out later. /// /// All right, you say, but why include the type parameters from the /// original function then? The answer is that codegen may need them /// when monomorphizing, and they may not appear in the upvars. A /// closure could capture no variables but still make use of some /// in-scope type parameter with a bound (e.g., if our example above /// had an extra `U: Default`, and the closure called `U::default()`). /// /// There is another reason. This design (implicitly) prohibits /// closures from capturing themselves (except via a trait /// object). This simplifies closure inference considerably, since it /// means that when we infer the kind of a closure or its upvars, we /// don't have to handle cycles where the decisions we make for /// closure C wind up influencing the decisions we ought to make for /// closure C (which would then require fixed point iteration to /// handle). Plus it fixes an ICE. :P /// /// ## Generators /// /// Generators are handled similarly in `GeneratorSubsts`.
