pub fn try_parse_reference_definition(
text: &str,
) -> Option<(usize, String, String, Option<String>)>Expand description
Try to parse a reference definition starting at the current position. Returns Some((bytes_consumed, label, url, title)) on success.
text may span multiple lines. The destination and title may each be
preceded by at most one newline (per CommonMark ยง4.7). Blank lines
terminate the definition: callers should stop the input at the first
blank line so the parser cannot cross one.
Syntax:
[label]: url "title"
[label]: <url> 'title'
[label]:
url
"title"
