file_type
Getting Started
File types are determined by examining a file or bytes against known file signatures and file extensions.
Signature, extension and media type data are provided by:
Example
Detect the file type from bytes:
use file_type::FileType;
let file_type = FileType::from_bytes(b"\xCA\xFE\xBA\xBE");
assert_eq!(file_type.extensions(), vec!["class"]);
Retrieve a file type from an extension:
use file_type::FileType;
let file_types = FileType::from_extension("png");
let file_type = file_types.first().expect("file format");
assert_eq!(file_type.media_types(), vec!["image/png"]);
Retrieve a file type from a media type:
use file_type::FileType;
let file_types = FileType::from_media_type("image/png");
let file_type = file_types.first().expect("file format");
assert_eq!(file_type.extensions(), vec!["png"]);
