Function std::fs::read_string [] [src]

pub fn read_string<P: AsRef<Path>>(path: P) -> Result<String>
🔬 This is a nightly-only experimental API. (fs_read_write #46588)

Read the entire contents of a file into a string.

This is a convenience function for using File::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.
