Function extract_vault_refs 

pub fn extract_vault_refs(text: &str) -> Vec<VaultRef>

Every [[wikilink]] and ![[transclusion]] in already-flattened text, in document order. The alias is everything after the first |; the fragment is everything after the first # in what is left, so [[Note|alias#Part]] has the alias alias#Part and no fragment. The text between the brackets cannot contain [.
