copy-metadata

cross-platform lib to copy metadata from one file to another.

• TOCTOU-safe – all metadata changes are applied through open file handles.
• No symlink following – only regular files and directories are supported.
• Cross-platform – uses fchmod/fchown/futimens on Unix and SetFileInformationByHandle, SetFileTime on Windows.

Usage

cargo add copy-metadata

functions:

fn copy_permission(from: impl AsRef<Path>, to: impl AsRef<Path>) -> io::Result<()>;
fn copy_time(from: impl AsRef<Path>, to: impl AsRef<Path>) -> io::Result<()>;
fn copy_metadata(from: impl AsRef<Path>, to: impl AsRef<Path>) -> io::Result<()>;
// copy_metadata = copy_permission + copy_time

or if you don't need to copy timestamps, you can disable the copy-time feature:

[dependencies]
copy-metadata = { version = "0.3", default-features = false }
