Function read_to_string

pub fn read_to_string<P: AsRef<Path>>(path: P) -> Result<String>

Reads the entire contents of a file into a string.

This is a convenience function for using File::open, Read::read_to_end, and String::from_utf8 (no_std_io does not support read_to_string).

Errors

This function will error if the path doesn’t exist, if the file is not valid UTF-8, or any other error according to OpenOptions::open.
