Oh, inspect has finally arrived! That will help a ton with debug logging.

Do you mind explaining? Maybe with the context of another languages equivalent?

[–] anlumo@feddit.de 0 points 7 months ago
let bar: Result<T, E> = ...;
let foo = bar.inspect(|value| log::debug("{}", value));

is equivalent to

let bar: Result<T, E> = ...;
let foo = bar.map(|value| {
    log::debug("{}", value);
    value
});
