fileidentifier v0.1.1
fileidentifier
This repo is a library for both Rust and Javascript (Node.js). It identify does not identify files using file extension but using magic number. So It helps you to check files better.
Installation
How to use
in Rust:
use std::fs;
use fileidentifier::check::{FileFormat, get_file_format, is_png};
fn main() -> Result<(), Box<dyn std::error::Error>> {
let file = fs::read("/usr/bin/whatever")?;
assert_eq!(FileFormat::Script, get_file_format(&file));
// or you can check a file format
let png = fs::read("/file/path/x.png")?;
assert_eq!(true, is_png(&png));
Ok(())
}
in Node.js:
const fi = require('fileidentifier')
let file = fs::readFileSync('/file/path/x.png')
console.log(fi.getFileFormat(file)) // It will print 'png'
//check a file format
console.log(fi.isPng(file)) // It will print true
