How to use Structured logging in Log crate?

[atomic kite]

Log crate describes KV feature that allows to associated structure data with log event. Following this example (https://github.com/rust-lang/log?tab=readme-ov-file#structured-logging) and using env_logger implementation, seems like provided KVs are ignored in the output. Does this feature require specific implementation to work?

info!(name=node_name.as_str(); "Starting application: {}", &local_addr);

output

[2025-03-08T19:34:36Z INFO gossipgrid] Starting application: 127.0.0.1:4109

env_logger has a unstable_kv feature flag, and methods that look relevant to logging structured data like DefaultFormat::write_kv are gated behind it. try enabling that feature and see if your structured data starts being logged
