Struct FormatMeta 

pub struct FormatMeta {
    pub id: FormatId,
    pub kind: FormatKind,
    pub extensions: &'static [&'static str],
    pub magics: &'static [MagicRule],
    pub priority: i16,
}

Registration metadata for one format.

Fields

id: FormatId

kind: FormatKind

extensions: &'static [&'static str]

Extensions without the leading dot, lowercase. e.g. ["gz", "tgz"].

magics: &'static [MagicRule]

priority: i16

Breaks ties when several formats share a magic. Higher wins.

The ZIP family is why this exists: jar, apk, docx, epub, odt and zip all begin PK\x03\x04, so longest-magic-wins cannot separate them. Rank the base format above its derivatives, and a bare stream resolves to the base while a derivative is reached by extension.
