macro.rs

1/// Combines multiple paths into a single valid path, handling overlapping slashes.
2///
3/// - Removes trailing slashes from the base path.
4/// - Removes leading slashes from subsequent paths to avoid duplication.
5/// - Supports multiple path segments for flexible usage.
6///
7/// # Parameters
8/// - `base`: The base path as a string slice. It serves as the starting point for the combined path.
9/// - `sub_path`: One or more subsequent paths as string slices. These are appended to the base path in order.
10///
11/// # Returns
12/// - `String`: The resulting combined path as a `String`, with platform-specific separators and cleaned of redundant slashes.
