Functions§

create_dir_all: Create a directory path if it does not exist. Will not throw an error if the directory already exists. Use to guarantee the filesystem state before a test runs.
get_file_contents: Read the contents of a file into a vector of bytes. Use for fixtures you never want to change.
get_rc_ref_cell_empty_vec: Get an empty vector wrapped in an Rc<RefCell<>>.
get_read_and_write_file: Get a read and write file handle. Use this to create temporary files for testing and comparison. The file will be created if it does not exist, and it will be overridden if it does.
get_read_only_file: Get a read-only file handle. Use for fixtures you never want to change.
get_reader_for_file: Get a BufReader for a file. Use for fixtures you never want to change.
get_writer_for_file: Get a writer for a file, creating the file if it does not exist. Use this to create temporary files for testing and comparison.
remove_file: Remove a file if it exists. Will not throw an error if the file does not exist.
sequential: Allow tests with side-effects to run without interfering with each other. The lock is released when the MutexGuard variable goes out of scope. Will ignore poison errors from other tests so that our test can continue even if theirs fails.
write_file_contents: Write bytes to a file, creating the file if it does not exist.
