In rust, this task is done using the file system. Let mut buffer = [0u8;. ( in file {}, file_path); Reading the contents of the file specified by the second argument. Reading a file requires two core pieces:
Let contents = fs::read_to_string (file_path).expect ( should have been able to read the file ); The first step in reading a file in rust is to open it. First, we add some more use statements to bring in relevant parts of the standard library: Let mut buffer = [0u8;. This is a convenience function for using file::open and read_to_string with fewer imports and without an intermediate variable.
