Function moq_publish_binary_snapshot 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn moq_publish_binary_snapshot(
    broadcast: u32,
    name: *const c_char,
    name_len: usize,
    config: *const moq_binary_config,
) -> i32

Create a binary snapshot track (lossy latest-value) on a broadcast: each payload supersedes the last, and a late joiner only sees the newest, e.g. the latest thumbnail of a camera.

The track is advertised in the broadcast’s catalog under binary.tracks.<name> with mode: snapshot (plus mime and compression when set), and the entry is retired when the track finishes or fails.

Returns a non-zero handle to the binary producer on success, or a negative code on failure, including a mux error when the catalog already carries an entry named name.

Safety

• The caller must ensure name is a valid pointer to name_len bytes and config a valid pointer.
