Function std::fs::read_link

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

Platform-specific behavior

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

Errors

• path is not a symbolic link.
• path does not exist.

let path = fs::read_link("a.txt")?;
