Fields

seat: Option<WlSeat>

manager_ext: Option<ExtDataControlManagerV1>

manager_wlr: Option<ZwlrDataControlManagerV1>

offer_mimes: HashMap<ObjectId, Vec<String>>

Advertised mimes per live offer.

selection: Option<DcOffer>

selection_changed: bool

Set on every selection event (the watch loop’s change edge).

finished: bool

Compositor told this device it is done (seat gone).

canceled: bool

The write path’s source lost the selection to another client.

serve: Vec<(String, Vec<u8>)>

Mime -> bytes served by the write path’s source.

write_no: u64

The write this source serves, as SERVED numbers it.

sync_done: bool

Implementations

impl DcState

fn take_manager(&mut self) -> Result<DcManager, String>

The bound manager, preferring ext over wlr; the loser is released.

fn on_data_offer(&mut self, id: ObjectId)

fn on_offer_mime(&mut self, id: ObjectId, mime_type: String)

fn on_selection(&mut self, offer: Option<DcOffer>)

fn on_primary_selection(&mut self, offer: Option<DcOffer>)

This bridge carries the regular selection only, but ext v1 still introduces an offer per primary-selection change; release it (unless the compositor reused the regular selection’s object) so it can’t pile up.

fn on_send(&mut self, mime_type: &str, fd: OwnedFd)
