Struct Attachment 

pub struct Attachment {
    pub name: String,
    pub mime: Option<String>,
    pub description: Option<String>,
    pub data: Vec<u8>,
}

One file-shaped payload attached to a container.

Distinct from AttachedPicture: an Attachment is an arbitrary byte blob with a filename — fonts (MKV application/x-truetype-font), thumbnail strips, subtitle fragments, README text — whereas AttachedPicture is the ID3v2/FLAC/MP4 cover-art pathway that carries a typed PictureType. MKV Attachments map cleanly onto this struct; MP4 meta boxes and Ogg METADATA_BLOCK_PICTURE are emitted as attached_pictures instead.

Fields

name: String

Original filename as stored in the container (no path stripping, no normalisation). Containers that don’t track a name still populate this — synthesise something stable like attachment_<id>.bin so callers always have a routing handle.

mime: Option<String>

IANA media type ("image/png", "application/x-truetype-font", …) when the container declares one. None means “unspecified” — callers are free to sniff the bytes.

description: Option<String>

Free-form description supplied by the tagger.

data: Vec<u8>

Raw attachment bytes exactly as stored in the container.

Trait Implementations

impl Clone for Attachment

fn clone(&self) -> Attachment

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Attachment

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Attachment

fn eq(&self, other: &Attachment) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
