Crate rfind_url

This crate provides a parser to search a string for URLs in reverse order.

All functionality is handled by the Parser struct which takes chars as input.

Examples

Text can be fed into the parser in reverse order:

use rfind_url::Parser;

let mut parser = Parser::new();

for c in "There is no URL here.".chars().rev() {
    assert_eq!(parser.advance(c), None);
}

The parser returns the length of the URL as soon as the last character of the URL is pushed into it. Otherwise it will return None:

use rfind_url::Parser;

let mut parser = Parser::new();

// Parser did not find any URLs
assert_eq!(parser.advance(' '), None);

// URLs are only returned once they are complete
for c in "ttps://example.org".chars().rev() {
    assert_eq!(parser.advance(c), None);
}

// Parser has detected a URL spanning the last 19 characters
assert_eq!(parser.advance('h'), Some(19));
