CnxFile struct

#include <include/Cnx/filesystem/File.h>

Cnx type used to manage reading and writing to/from a file, the buffering associated with the file, and closing it when it's no longer used.

Example:

#include <Cnx/filesystem/File.h>

void example(void) {
    let_mut maybe_file = cnx_file_open("my_file.txt");
    cnx_assert(cnx_result_is_ok(maybe_file), "Failed to open my_file.txt");
    CnxScopedFile file = cnx_result_unwrap(maybe_file);
    let my_important_number = 42;
    let my_important_float 24.0F;
    cnx_file_println(&file, "number: {}, float: {}", my_important_number, my_important_float);

    let_mut maybe_file2 = cnx_file_open("my_other_file.txt");
    cnx_assert(cnx_result_is_ok(maybe_file2), "Failed to open my_other_file.txt");
    CnxScopedFile file2 = cnx_result_unwrap(maybe_file2);
    let_mut maybe_read = cnx_file_read_line(&file2);
    if(cnx_result_is_ok(maybe_read)) {
        CnxScopedString str = cnx_result_unwrap(maybe_read);
        // do something with the line read from `my_other_file.txt`
    }

    // files automatically closed when they leave scope because they were declared as
    // `CnxScopedFile`
}
