Enum Language 

pub enum Language {
    Iso639([u8; 3]),
    Other(u16),
}

A track language.

Variants

Iso639([u8; 3])

A packed ISO 639-2/T code, three lowercase letters, such as und.

Other(u16)

A code that is not a packed ISO 639-2/T code: a QuickTime Macintosh language code (below 0x400, or 0x7FFF for unspecified), or a packed code with letters outside a-z.

Implementations

impl Language

pub fn from_code(code: u16) -> Self

Decode the 16-bit mdhd language field.

pub fn iso639(&self) -> Option<&str>

The packed ISO 639-2/T code as a string, when the track has one. A Macintosh code gives None. Language::iso639_mapped maps it.

pub fn iso639_mapped(&self) -> Option<&str>

The ISO 639-2/T code, with a Macintosh code mapped through the QuickTime table.

None when the table has no entry: 0x7FFF (unspecified), a code from 95 to 127, a code above 138, or a packed code with letters outside a-z.
