file-format

File format library for Rust.

This crate is for determining binary-based file formats.

Example

Determines from a file:

use file_format::FileFormat;

let format = FileFormat::from_file("fixtures/application/sample.zip").unwrap();
assert_eq!(format, FileFormat::Zip);
assert_eq!(format.name(), "ZIP");
assert_eq!(format.media_type(), "application/zip");
assert_eq!(format.extension(), "zip");

Determines from bytes:

use file_format::FileFormat;

let format = FileFormat::from_bytes(&[0xFF, 0xD8, 0xFF, 0xEE]);
assert_eq!(format, FileFormat::JointPhotographicExpertsGroup);
assert_eq!(format.name(), "Joint Photographic Experts Group");
assert_eq!(format.media_type(), "image/jpeg");
assert_eq!(format.extension(), "jpg");
