Function gen_epub_book::ops::parse_descriptor

pub fn parse_descriptor<R: Read>(
    desc: &'static str, 
    from: &mut R, 
    separator: &str, 
    free_date: bool
) -> Result<Vec<BookElement>, Error>

Parse the whole descriptor with a specified separator with the specified rigidness, stopping at the first encountered error.

Uses BookElement::parse(), so it inherits all errors from there, adding only the error from splitting lines.

Filters out non-describing lines.

Examples

assert_eq!(parse_descriptor("string input", &mut &b"\
        This is a very simple thing that should prove unproblematic to parse\n\
