Function resolve_path

pub fn resolve_path(file: &str, path: &str) -> String

Experimental utility for resolving the manifest path.

Arguments

• file - the current script file path (obtained with file!() macro);
• path - the “path/to/manifest.json” string slice.

Panics

This function might panic in various occasions:

• if file has no parent directory (e.g. “src/main.rs” parent would be “src”);
• if it fails to find the file first segment somehow (e.g. “path/to/file” => “path”);
• if the first file path Component is neither RootDir nor Normal;
• if final result fails to be canonicalized.

The last situation might occur if the final path doesn’t really lead to any existing file/directory. Or perhaps, because this function has a bug! In this case, please open an issue at our GitHub repository!

Example

example/
|-- .dist/
|   |-- .vite/
|   |   |-- manifest.json
|-- src/
|   |-- main.rs

// example/src/main.rs
let manifest_path = resolve_path(file!(), "../dist/.vite/manifest.json");
let mut vite_config = ViteConfig::new_with_defaults(&manifest_path);

println!("{manifest_path}");
// C:/totally/absolute/path/to/example/.dist/.vite/manifest.json
