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 | //! ``` |
