Enum mp4ameta::DataIdent

pub enum DataIdent {
    Fourcc(Fourcc),
    Freeform {
        mean: String,
        name: String,
    },
}

An identifier for data.

Variants

Fourcc(Fourcc)

A standard identifier containing a 4 byte atom identifier.

Freeform

An identifier of a freeform (----) atom containing owned mean and name strings.

Fields of Freeform

mean: String

The mean string, typically in reverse domain notation.

name: String

The name string used to identify the freeform atom.
