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", &"r", 1); //Hulro
writer.find_replace(&"o", &"ooooooo"); //Hulrooooooo
writer.find_replace_all(&"o", &"d"); //Hulrddddddd
let reader = FileReader::open(&test_path);
let content = reader.read_to_string();
assert_eq!(content, "Hulrddddddd");

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.
