Crate ra_ap_hir_ty[−][src]
The type system. We currently use this to infer types for completion, hover information and various assists.

Modules
db | The home of |
diagnostics | Type inference-based diagnostics. |
display | The |
method_resolution | This module is concerned with finding methods that a given type provides. For details about how this works in rustc, see the method lookup page in the rustc guide and the corresponding code mostly in librustc_typeck/check/method/probe.rs. |
primitive | A few helper functions for dealing with primitives. |
traits | Trait solving using Chalk. |
Macros

Structs
AdtId | The id for an Abstract Data Type (i.e. structs, unions and enums). |
BoundVar | Identifies a particular bound variable within a binder.
Variables are identified by the combination of a |
CallableSig | A function signature as seen by type inference: Several parameter types and one return type. |
DebruijnIndex | References the binder at the given depth. The index is a de
Bruijn index, so it counts back through the in-scope binders,
with 0 being the innermost binder. This is used in impls and
the like. For example, if we had a rule like |
FnSubst | A wrapper for the substs on a Fn. |
InferenceResult | The result of type inference: A mapping from expressions and patterns to types. |

Mutability | Whether a type is mutable or not. |
Safety | Whether a function is safe or not. |
Scalar | Types of scalar values. |

TyVariableKind | Represents some extra knowledge we may have about the type variable. |

TypeWalk | This allows walking structures that contain types to do something with those
types, similar to Chalk’s |
Functions
