Change the name's type `String` to `Cow<'static, str>`. This allows the library user to prevent string allocation from static strings, which is how most crates use it. This is an API breaking change. Signed-off-by: Manos Pitsidianakis <[email protected]>

There was a problem hiding this comment.
Hm... This is the only use and requires ownership. So should we maybe just drop it from the daemon struct and make it part of the start_daemon function (as a String that can be moved through)?
Though, overall, I think this is a lot of code churn (for everyone using this) and additional complexity for very little gain.
