Enum How 

pub enum How {
    Inode,
    StrongMagic,
    Name,
    Magic,
    Fallback,
}

How the answer was reached. Kept because the difference matters to a caller: a type from a filename is a statement about intent, one from contents is a statement about bytes, and the fallbacks are neither.

Variants

Inode

It is not an ordinary file.

StrongMagic

A magic rule the database marks 80 or above.

Name

A filename rule.

Magic

A weaker magic rule.

Fallback

Nothing recognised it: empty, text, or bytes.
