tab_spaces = 2 not work with match statement

[getong]

cat ~/.config/rustfmt/rustfmt.toml 
edition = "2021"

format_strings = true
spaces_around_ranges = true
tab_spaces = 2

But the config does not work with match statement

  match swarm.select_next_some().await {
            SwarmEvent::NewListenAddr { listener_id, address } => info!("NewListenAddr: {listener_id:?} | {address:?}"),
            SwarmEvent::ConnectionEstablished {
                peer_id,
                connection_id,
                endpoint,
                num_established,
                concurrent_dial_errors,
                established_in } => info!("ConnectionEstablished: {peer_id} | {connection_id} | {endpoint:?} | {num_established} | {concurrent_dial_errors:?} | {established_in:?}"),
            SwarmEvent::Dialing { peer_id, connection_id } => info!("Dialing: {peer_id:?} | {connection_id}"),
            SwarmEvent::Behaviour(AgentEvent::Identify(event)) => match event {
                IdentifyEvent::Sent { peer_id, .. } => info!("IdentifyEvent:Sent: {peer_id}"),
                IdentifyEvent::Pushed { peer_id, info, .. } => info!("IdentifyEvent:Pushed: {peer_id} | {info:?}"),
                IdentifyEvent::Received { peer_id, info, .. } => {
                    info!("IdentifyEvent:Received: {peer_id} | {info:?}");
                    peers.insert(peer_id, info.clone().listen_addrs);

                    for addr in info.clone().listen_addrs {
                        let agent_routing = swarm.behaviour_mut().register_addr_kad(&peer_id, addr.clone());

which should be

  match swarm.select_next_some().await {
    SwarmEvent::NewListenAddr { listener_id, address } => info!("NewListenAddr: {listener_id:?} | {address:?}"),
    SwarmEvent::ConnectionEstablished {
        peer_id,
        connection_id,
        endpoint,
        num_established,
        concurrent_dial_errors,
        established_in } => info!("ConnectionEstablished: {peer_id} | {connection_id} | {endpoint:?} | {num_established} | {concurrent_dial_errors:?} | {established_in:?}"),
    SwarmEvent::Dialing { peer_id, connection_id } => info!("Dialing: {peer_id:?} | {connection_id}"),
    SwarmEvent::Behaviour(AgentEvent::Identify(event)) => match event {
        IdentifyEvent::Sent { peer_id, .. } => info!("IdentifyEvent:Sent: {peer_id}"),
        IdentifyEvent::Pushed { peer_id, info, .. } => info!("IdentifyEvent:Pushed: {peer_id} | {info:?}"),
        IdentifyEvent::Received { peer_id, info, .. } => {
          info!("IdentifyEvent:Received: {peer_id} | {info:?}");
          peers.insert(peer_id, info.clone().listen_addrs);

          for addr in info.clone().listen_addrs {
              let agent_routing = swarm.behaviour_mut().register_addr_kad(&peer_id, addr.clone());

Thanks but going to close as a duplicate of #3416/#3863/etc.

You'll either want to manually break up that that long string arg to the info! call (on the second arm of the top level match expression), or give rustfmt permission to do it for you by setting format_strings=true

[getong]

I already set it with format_strings=true, you can see it at the beginning of this issue text.

so you do (though no indication of which version & toolchain you're using, sometimes people attempt to use unstable options from stable which aren't operative). however, there's other issues with your input and "should be" output that are indicative of broader skipped formatting; it's not just the opening indentation on each line.

I'd bet that if you made some more noticeable changes that were intentionally misformatted then you'll notice that the match expression is being skipped, e.g.

match                                swarm               .              select_next_some()        .await {

if you are on nightly then you may need to try version=Two to get access to some newer formatting as well

$ cat ~/.config/rustfmt/rustfmt.toml 
edition = "2021"

format_strings = true
spaces_around_ranges = true
tab_spaces = 2
version=Two
