file-format

File format library for Rust.

This crate is for recognizing binary-based file formats.

Examples

Determines from a file:

use file_format::FileFormat;

let format = FileFormat::from_file("fixtures/image/sample.jpg").unwrap();
assert_eq!(format.media_type(), "image/jpeg");
assert_eq!(format.extension(), "jpg");

Determines from bytes:

use file_format::FileFormat;

let format = FileFormat::from_bytes(&[0x66, 0x4C, 0x61, 0x43]);
assert_eq!(format.media_type(), "audio/x-flac");
assert_eq!(format.extension(), "flac");
