Expand description
Specifies callbacks for JACK.
Provided methods
fn thread_init(&self, _: &Client)
fn thread_init(&self, _: &Client)
Called just once after the creation of the thread in which all other callbacks will be handled.
It does not need to be suitable for real-time execution.
fn shutdown(&mut self, _status: ClientStatus, _reason: &str)
fn shutdown(&mut self, _status: ClientStatus, _reason: &str)
Called when the JACK server shuts down the client thread. The function must be written as if it were an asynchronous POSIX signal handler — use only async-safe functions, and remember that it is executed from another thread. A typical function might set a flag or write to a pipe so that the rest of the application knows that the JACK client thread has shut down.
Called whenever “freewheel” mode is entered or leaving.
fn sample_rate(&mut self, _: &Client, _srate: Frames) -> Control
fn sample_rate(&mut self, _: &Client, _srate: Frames) -> Control
Called whenever the system sample rate changes.
fn client_registration(&mut self, _: &Client, _name: &str, _is_registered: bool)
fn client_registration(&mut self, _: &Client, _name: &str, _is_registered: bool)
Called whenever a client is registered or unregistered
fn port_registration(
&mut self,
_: &Client,
_port_id: PortId,
_is_registered: bool
)
fn port_registration(
&mut self,
_: &Client,
_port_id: PortId,
_is_registered: bool
)
Called whenever a port is registered or unregistered
Called whenever a port is renamed.
Called whenever ports are connected/disconnected to/from each other.
fn graph_reorder(&mut self, _: &Client) -> Control
fn graph_reorder(&mut self, _: &Client) -> Control
Called whenever the processing graph is reordered.
