Function resolve_chain

pub fn resolve_chain(
    base: Option<&Url>,
    chain: &[String],
    reference: &str,
) -> Option<String>
Expand description

Resolve a BaseURL chain (outermost first) followed by a segment reference. Each entry is joined onto the running result, so a relative entry composes with the ones above it and an absolute one resets the chain. Empty and whitespace-only entries are skipped — ISO/IEC 23009-1 §5.6.5 makes several BaseURLs alternates for the same level, so an empty one contributes nothing. None for a control character or whitespace in any entry or the reference (first_forbidden_char), for an input that names the synthetic scheme, or for a join error. With base == None a relative outcome stays relative and contained (see the module docs).
