Function validate_only 

pub fn validate_only(content_dir: &Path) -> Result<()>

Runs content schema validation without building the site.

Returns Ok(()) when all files pass, or an error listing every validation failure.

Examples

use ssg::content::validate_only;
use tempfile::tempdir;

// No schema file ⇒ trivial pass.
let dir = tempdir().unwrap();
assert!(validate_only(dir.path()).is_ok());
