Today I wrota program to catch group capture in a generic way: <div class="highlight highlight-source-rust notranslate position-relative overflow-auto" dir="auto" data-snippet-clipboard-copy-content="let mut result = vec![]; for c in regex.captures_iter(arg) { let mut cap = vec![]; for m in c.iter() { if let Some(m) = m { // how to get the name? cap.push(<{ "name": ..., "text": m.as_str() }>); } cap.push(<null>); } result.push(cap); }"> let mut result = vec ! [ ] ; for c in regex . captures_iter ( arg ) { let mut cap = vec ! [ ] ; for m in c . iter ( ) { if let Some ( m ) = m { // how to get the name? cap . push ( < { "name" : ... , "text" : m . as_str ( ) } > ) ; } cap . push ( < null > ) ; } result . push ( cap ) ; } When the match is not named, I'm OK to attach a null name field. But is it possible to get the name of named capture group? Related - #955 and thus cc @BurntSushi @01mf02

In the future, please provide an MRE. It looks like you should be able to just do for (name, m) in regex.capture_names().zip(c.iter()) { via Regex::capture_names .

How do I get the name for each capture group when using `Captures::iter`? · rust-lang regex
