Macro nom::eof

macro_rules! eof {
    ($i:expr,) => { ... };
}

eof!() returns its input if it is at the end of input data

This combinator works with the AtEof trait that input types must implement. If an input type's at_eof method returns true, it means there will be no more refills (like what happens when buffering big files).

When we're at the end of the data and at_eof returns true, this combinator will succeed
