Function std::fs::read_link

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

Reads a symbolic link, returning the file that the link points to.

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.

Errors

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

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

Examples

use std::fs;

fn main() -> std::io::Result<()> {
    let path = fs::read_link("a.txt")?;
    Ok(())
}
