Function `eof`

fn eof<I: Input + Clone, E: ParseError<I>>(input: I) -> IResult<I, I, E>

returns its input if it is at the end of input data

When we're at the end of the data, this combinator will succeed

# use std::str;
# use nom::{Err, error::ErrorKind, IResult};
# use nom::combinator::eof;

# fn main() {
let parser = eof;
assert_eq!(parser("abc"), Err(Err::Error(("abc", ErrorKind::Eof))));
assert_eq!(parser(""), Ok(("", "")));
# }
