Crate file_type

file_type FileType

Getting Started

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

Additional information on PRONOM file types can be found at The National Archives

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.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.name(), "Text");
assert_eq!(file_type.media_types(), vec!["text/plain"]);
assert_eq!(file_type.extensions(), Vec::<String>::new());
