Function verify_path 

pub fn verify_path(
    path: &[u8],
    prot: PathProtection,
    is_symlink: bool,
) -> Result<(), Error>

Verify every /-separated component of path is safe to materialize.

path is a repository-relative slash-separated tree/index path. Each component is checked with verify_path_component. is_symlink is the mode of the leaf entry being written and gates the .gitmodules checks, matching Git’s verify_path().

Errors

Returns Error::InvalidPath for the first forbidden component.
