Function rama::tls::rustls::dep::pemfile::read_one

pub fn read_one(rd: &mut dyn BufRead) -> Result<Option<Item>, Error>

Extract and decode the next PEM section from rd.

• Ok(None) is returned if there is no PEM section read from rd.
• Underlying IO errors produce a Err(...)
• Otherwise each decoded section is returned with a Ok(Some(Item::...))

You can use this function to build an iterator, for example: for item in iter::from_fn(|| read_one(rd).transpose()) { ... }
