//! This module reexports the primitive types to allow usage that is not
|
|
//! possibly shadowed by other declared types.
|
|
//!
|
|
//! This is normally only useful in macro generated code.
|
|
//!
|
|
//! An example of this is when generating a new struct and an impl for it:
|
|
//!
|
|
//! ```rust,compile_fail
|
|
//! pub struct bool;
|
|
//!
|
|
//! impl QueryId for bool {
|
|
//! const SOME_PROPERTY: bool = true;
|
|
//! }
|
|
//!
|
|
//! # trait QueryId { const SOME_PROPERTY: core::primitive::bool; }
|
|
//! ```
|
|
//!
|
|
//! Note that the `SOME_PROPERTY` associated constant would not compile, as its
|
|
//! type `bool` refers to the struct, rather than to the primitive bool type.
|
|
//!
|
|
//! A correct implementation could look like:
|
|
//!
|
|
//! ```rust
|
|
//! # #[allow(non_camel_case_types)]
|
|
//! pub struct bool;
|
|
//!
|
|
//! impl QueryId for bool {
|
|
//! const SOME_PROPERTY: core::primitive::bool = true;
|
|
//! }
|
|
//!
|
|
//! # trait QueryId { const SOME_PROPERTY: core::primitive::bool; }
|
|
//! ```
