[][src]Function build_helper::up_to_date

pub fn up_to_date(src: &Path, dst: &Path) -> bool
🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Returns whether dst is up to date given that the file or files in src are used to generate it.

Uses last-modified time checks to verify this.
