Enum MediaKind 

pub enum MediaKind {
    Image,
    Video,
    Audio,
}

What a block-level media placeholder actually is, so a frontend knows which widget to build over the reserved rows: a raster, a movie player, or a transport with no picture at all. Core classifies and stops there — it opens nothing, so this is a statement about the markup, not about a file it has verified exists or can decode.

Variants

Image

A ![](…) / <img> / <picture> — a still picture.

Video

An HTML <video>. Markdown and Djot spell no video of their own, so this only ever arrives through html_elements promotion (or a ::video{…} directive a host app maps itself, which core reports as a directive).

Audio

An HTML <audio> — a transport with no picture, so a frontend gives it a fixed control height rather than measuring an aspect ratio.
