Function std::fs::read_link1.0.0 [] [src]

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.


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


use std::fs;

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