pub fn read<P: AsRef<Path>>(path: P) -> Result<Vec<u8>>
Expand description
Reads the entire contents of a file into a bytes vector.
This is a convenience function for using File::open
and read_to_end
with fewer imports and without an intermediate variable.
§Errors
This function will return an error if path
does not already exist.
Other errors may also be returned according to OpenOptions::open
.
While reading from the file, this function handles io::ErrorKind::Interrupted
with automatic retries. See io::Read documentation for details.
