Implementations§

Source§

impl StaleItem

Source

fn log(&self)

Use the log crate to log a hopefully helpful message in diagnosing what file is considered stale and why. This is intended to be used in conjunction with CARGO_LOG to determine why Cargo is recompiling something. Currently there’s no user-facing usage of this other than that.
