1//! URI handling utilities for Cloudreve v4 API
2//!
3//! This module provides utilities for converting file paths to the Cloudreve URI format
4//! and validating URIs according to the Cloudreve API specification.

12/// * `path` - File path (can be absolute, relative, or already a URI)
13///
14/// # Returns
15/// A properly formatted Cloudreve URI string

17/// # Examples
18/// ```
