Struct EventPair 

pub struct EventPair { /* private fields */ }

Lightweight cross-process event signalling.

Unix: two independent pipes provide bidirectional wake-up. Windows: two named auto-reset events provide bidirectional wake-up.

Implementations

impl EventPair

pub fn new() -> Result<EventPair, Error>

Create two pipes. Returns Err if pipe(2) fails.

pub unsafe fn from_fds( daw_to_host_read: i32, host_to_daw_write: i32, ) -> EventPair

Safety

daw_to_host_read and host_to_daw_write must be valid, already-open file descriptors inherited from the parent process.

pub fn daw_write_fd(&self) -> i32

pub fn daw_read_fd(&self) -> i32

pub fn host_read_fd(&self) -> i32

pub fn host_write_fd(&self) -> i32

pub fn signal_host(&self) -> Result<(), Error>

DAW wakes the host.

pub fn wait_host(&self, timeout: Duration) -> Result<(), Error>

DAW waits for host completion (with timeout).

pub fn wait_daw(&self, timeout: Duration) -> Result<(), Error>

Host waits for DAW wake (with timeout).

pub fn signal_daw(&self) -> Result<(), Error>

Host signals completion to DAW.

pub fn close_daw_unused(&mut self)

Close the file descriptors that the DAW side does not need.

pub fn close_host_unused(&mut self)

Close the file descriptors that the host side does not need.

Trait Implementations

impl Drop for EventPair

Available on Unix only.

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
