Crate file_format[−][src]
Expand description
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");Supported file formats
