Struct JackBackend 

pub struct JackBackend { /* private fields */ }

JACK host backend with deterministic provider data.

Implementations

impl JackBackend

pub fn new(clients: Vec<JackClient>) -> Self

Builds a live backend over the given JACK clients.

The backend reports itself as connected (true) and derives its capability set from the supplied clients’ audio, MIDI, and duplex ports.

pub fn fake() -> Self

Builds an offline backend seeded with the SIM default client.

The backend reports itself as disconnected and adds the HostBackendCapability::Offline and HostBackendCapability::Fake capabilities, making it suitable for validation without a running JACK server.

pub fn list_clients(&self) -> &[JackClient]

Returns the JACK clients registered with this backend.

pub fn sim_client(&self) -> Option<&JackClient>

Returns the client named SIM, if one is registered.

pub fn open_sim_client(&self, capacity: usize) -> Result<HostOpenStream>

Opens a duplex stream on the SIM client with a bounded buffer of capacity frames.

Errors

Returns an error if no SIM client is registered or if the open request is rejected.
