1//! This module reexports the primitive types to allow usage that is not
2//! possibly shadowed by other declared types.
3//!
4//! This is normally only useful in macro generated code.
5//!
6//! An example of this is when generating a new struct and an impl for it:
7//!
8//! ```rust,compile_fail
9//! pub struct bool;
10//!
11//! impl QueryId for bool {
12//! const SOME_PROPERTY: bool = true;
13//! }
14//!
15//! # trait QueryId { const SOME_PROPERTY: ::core::primitive::bool; }
16//! ```
17//!
18//! Note that the `SOME_PROPERTY` associated constant would not compile, as its
19//! type `bool` refers to the struct, rather than to the primitive bool type.
20//!
21//! A correct implementation could look like:
22//!
23//! ```rust
24//! # #[allow(non_camel_case_types)]
25//! pub struct bool;
26//!
27//! impl QueryId for bool {
28//! const SOME_PROPERTY: ::core::primitive::bool = true;
29//! }
30//!
31//! # trait QueryId { const SOME_PROPERTY: ::core::primitive::bool; }
32//! ```
33//!
34//! We also used `::core` instead of `core`, because `core` can be
35//! shadowed, too. Paths, starting with `::`, are searched in
36//! the [extern prelude] since Edition 2018.
