Crate of the week: serde-encrypt

This week's crate is serde-encrypt, a library that adds encryption to all Serialize impls.

написал пост о проблемах background обработки и о библиотеке, которую я написал для этого
https://www.badykov.com/rust/2021/06/27/fang/

Коллеги, подскажите, пожалуйста, как использовать (https://github.com/tokio-rs/tracing) чтобы в логах выводилась информация с файлом и номером строки где пишется лог. pretty() эту инфу выводит, но слишком pretty, так что на лог по 4 строки уходит. Я хочу лог в одну строчку, но с инфой о файле. Есть такая возможность?
Вот так инитиализирую:

    tracing_subscriber::fmt()
        .with_level(true)
        .with_thread_names(true)
        .with_max_level(tracing::Level::TRACE)
        .init();

Если каждый объект в структуре зависит от предыдущего и требует действий перед дропом, то для правильного дропа их стоит расположить в обратном порядке, а для каждого типа в структуре реализовать Drop? Возможно ли самому указать порядок дропа в структуре?

The fields of a struct are dropped in declaration order.

т.е. с первого?

сверху вниз, короче

странно, конечно

Логично
Ты же читаешь сверху вниз ,а не снизу вверх
