Blocking read
This trait is available if embedded-hal is built with the "unproven"
feature.

sourcefn read(&mut self, buffer: &mut [u8]) -> Result<(), Self::Error>
fn read(&mut self, buffer: &mut [u8]) -> Result<(), Self::Error>
Reads enough bytes from hardware random number generator to fill buffer
If any error is encountered then this function immediately returns. The contents of buf are unspecified in this case.
If this function returns an error, it is unspecified how many bytes it has read, but it will never read more than would be necessary to completely fill the buffer.
