To access an array element, we specify the array name followed by a pair of [] brackets in which we put the index of the element. println!("The first element is: {}", vals[0]); We print the first element. printl

create an iterator that begins with a zero value, take all elements lower than n, a number passed as parameter by the user - as a reminder, if we explicit the final of the iterator, the compiler could decide to compute the final number at compile time, and store it in the executable ...
The ndarray crate provides an n-dimensional container for general elements and for numerics. Please read the API documentation on docs.rs or take a look at the quickstart tutorial. Highlights Generic 1, 2, ..., n-dimensional arrays Owned arrays and array views Slicing, also with arbitrary ste...

Another question is that the expected behavior is that the entire project is compiled intact by cargo and then linked with other parts of the project, but it seems that xmake will create an additional cargo project and then only include my add_files("src /lib.rs") added lib.rs?
