Function get_tracked_file

atomic-core/src/record/workflow/collect.rs:543–566

Get the pristine state for a single file. Looks up a file's tracked state in the pristine database. # Arguments `txn` - Read transaction for pristine database `path` - Path to look up # Returns `Some(TrackedFile)` if the file is tracked, `None` otherwise. # Example ```rust,ignore if let Some(tracked) = get_tracked_file(&txn, "src/main.rs")? { println!("File {} has inode {:?}", tracked.path,

(txn: &T, path: &str)
