Crate file_rw

file_rw

file_rw is a Rust library for efficient file reading and writing.

It provides the following modules:

• file: File operations
• read: File reading capabilities
• write: File writing capabilities

Reexports

The library reexports the FileReader and FileWriter types for external use.

Examples

use file_rw::{FileReader, FileWriter};
use tempfile::tempdir;

let tempdir = tempdir().unwrap();
let tempdir_path = tempdir.path();
let test_path = tempdir_path.join("test.txt");
let mut writer = FileWriter::open(&test_path);
writer.append("Hello World!"); //Hello World!
writer.overwrite("Hello"); //Hello
writer.write("Hullo"); //Hullo

writer.find_replace_nth("l", "y", 0); //Huylo
writer.find_replace("u", "e"); //Heylo
writer.find_replace("lo", "yyy"); //Heyyyy
writer.find_replace_all("y", "i"); //Heiiii
writer.find_replace("e", "i"); //Hiiiii
let reader = writer.to_reader();
let content = reader.read_to_string();
assert_eq!(content, "Hiiiii");

Structs

• FileReader
  The FileReader struct represents a file reader that provides high-performance file reading capabilities. It uses memory mapping for efficient access to file data.
• FileWriter
  FileWriter is a structure that allows writing to a file. It uses memory-mapped files for efficient file manipulation.
