Implementations

impl StaleItem

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.

Trait Implementations

impl Clone for StaleItem

fn clone(&self) -> StaleItem

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StaleItem

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
