file_type

Getting Started

A file type. The file type is determined by examining the file or bytes against known file signatures and file extensions.

Signatures, extensions and media type data are provided by:

• The National Archives PRONOM
• Apache HTTPD
• Linguist

Example

Detect a Java class file from bytes:

use file_type::FileType;

let file_type = FileType::from_bytes(b"\xCA\xFE\xBA\xBE");
assert_eq!(file_type.id(), "x-fmt/415");
assert_eq!(file_type.name(), "Java Class File");
assert_eq!(file_type.media_types(), Vec::<String>::new());
assert_eq!(file_type.extensions(), vec!["class"]);

Detect text from bytes:

use file_type::FileType;

let file_type = FileType::from_bytes(b"hello, world\n");
assert_eq!(file_type.id(), "default/1");
assert_eq!(file_type.name(), "Text");
assert_eq!(file_type.media_types(), vec!["text/plain"]);
assert_eq!(file_type.extensions(), Vec::<String>::new());
