external libraries and thus also works in#[no_std]environments. It works by collecting all functions annotated with a#[test_case]attribute and then invoking a user-specified runner function with the list of tests as an argument. Thus, it gives the implementation maximal control over the test ...
The challenge in this chapter is to implement theheadprogram, which will print the first few lines or bytes of one or more files.This is a good way to peek at the contents of a regular text file and is often a much better choice thancat.When faced with a directory of something like ...
