Function sgx_tstd::untrusted::fs::read

pub fn read<P: AsRef<Path>>(path: P) -> Result<Vec<u8>>

Read 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. It pre-allocates a buffer based on the file size when available, so it is generally faster than reading into a vector created with Vec::new().

Errors

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.
