//! Cross-platform path string helpers.

use std::path::Path;

/// Render `path` with forward-slash separators on every platform.
///
/// Use this for path strings that go into JSON or other machine-readable
/// artifacts, so the artifact bytes are identical between Linux/macOS
/// (which already use `/`) and Windows (where `Path::display()` would
/// emit `\`). Drive letters and UNC prefixes survive — only the separator
/// changes (`C:\foo\bar` → `C:/foo/bar`, `\\srv\sh\f` → `//srv/sh/f`).
