Struct ruplacer::FilePatcher

pub struct FilePatcher { /* private fields */ }

Run replacement query on a given file

Example, assuming the data.txt file contains ‘This is my old car’

use ruplacer::{Console, FilePatcher, Query};
use std::path::PathBuf;

let file = PathBuf::from("data.txt");
let query = Query::substring("old", "new");
let console = Console::new();
let file_patcher = FilePatcher::new(&console, &file, &query).unwrap();
file_patcher.unwrap().run().unwrap();

let new_contents = std::fs::read_to_string("data.txt").unwrap();
assert_eq!(new_contents, "This is my new car.");
