Function std::fs::canonicalize

pub fn canonicalize<P: AsRef<Path>>(path: P) -> Result<PathBuf>

Returns the canonical form of a path with all intermediate components normalized and symbolic links resolved.

Platform-specific behavior

This function currently corresponds to the realpath function on Unix and the CreateFile and GetFinalPathNameByHandle functions on Windows. Note that, this [may change in the future][changes]. [changes]: ../io/index.html#platform-specific-behavior

Errors

This function will return an error in the following situations, but is not limited to just these cases:

• path does not exist.
• A component in path is not a directory.

Examples

use std::fs;

let path = fs::canonicalize("../a/../foo.txt")?;
