Rust documentation tests are typically examples of usage of any
item (e.g. function, struct, module...). They are very convenient
because they are just written alongside the documentation, e.g.:
/// Sums two numbers.
///
/// # Examples
///
/// ```
/// assert_eq!(mymod::f(10, 20), 30);
/// ```
pub fn f(a: i32, b: i32) -> i32 {
a + b
}
These scripts are used to transform Rust documentation tests into
KUnit tests, so that they can be run in-kernel. In turn, this allows
us to run tests that use kernel APIs.
In particular, the test builder receives `rustdoc`-generated tests,
parses them and stores the result. Then, the test generator takes
the saved results and generates a KUnit suite where each original
documentation test is a test case.
For the moment, this is only done for the `kernel` crate, but
the plan is to generalize it for other crates and modules.
