[][src]Function build_helper::mtime

pub fn mtime(path: &Path) -> SystemTime
🔬 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 the last-modified time for path, or zero if it doesn't exist.
