Function replace_str_in_files 

pub fn replace_str_in_files<P: AsRef<Path>>(
    path: P,
    old_string: &str,
    new_string: &str,
)

Replaces all occurrences of a string in all files within a directory (including subdirectories).

Arguments

• path - Path to the directory or file where the replacements will be performed (can be a &str, String, Path, or std::path::PathBuf).
• old_string - The substring to find and replace in all files.
• new_string - The replacement string.

Note

This function will not panic if a single read/write fails (since this function may pull in private, inaccessible files). However, a warning will be printed to stderr.

Examples

use file_io::replace_str_in_files;

let dir = Path::new("/path/to/folder");

// Replace "foo" with "bar" in all files within the "/path/to/folder/" directory (including
// subdirectories).
replace_str_in_files(dir, "foo", "bar");
