Function version_sync::check_html_root_url

pub fn check_html_root_url(
    path: &str,
    pkg_name: &str,
    pkg_version: &str
) -> Result<(), String>

Check version numbers in html_root_url attributes.

This function parses the Rust source file in path and looks for html_root_url attributes. Such an attribute must specify a valid URL and if the URL points to docs.rs, it must be point to the documentation for pkg_name and pkg_version.

Errors

If any attribute fails the check, an Err is returned with a succinct error message. Status information has then already been printed on stdout.
