I have code which interracts with C via bindings. In it I have this:
let a1: *const i8 = get_data(); let size1 = get_size_of_data(); let a2 = ::std::slice::from_raw_parts(a2, size1);
I need to write
a1 into a binary file. The size or length of the data is known.
let mut f1 = File::create("my_file.data").unwrap(); // ??? f1.write_all(a2).expect("unable to write binary data to file"); // ??? f1.write_all(a2.as_bytes).expect("unable to write binary data to file");
and nothing has compiled.
How to do it?
