pub fn read_to_string<P: AsRef<Path>>(path: P) -> Result<String>
Read the entire contents of a file into a string.
This is a convenience function for using SgxFile::open and read_to_string with fewer imports and without an intermediate variable.
This function will return an error if
path does not already exist.
Other errors may also be returned according to OpenOptions::open.
It will also return an error if it encounters while reading an error of a kind other than ErrorKind::Interrupted, or if the contents of the file are not valid UTF-8.
