Constant methods for core::AsyncArray

Required Methods§

source

fn as_raw_AsyncArray(&self) -> *const c_void

Provided Methods§

source

fn get(&self, dst: &mut impl ToOutputArray) -> Result<()>

Fetch the result.

§Parameters
  • dst:[out] destination array

Waits for result until container has valid result. Throws exception if exception was stored as a result.

Throws exception on invalid container state.

Note: Result or stored exception can be fetched only once.

source

fn get_with_timeout( &self, dst: &mut impl ToOutputArray, timeout_ns: i64, ) -> Result<bool>

Retrieving the result with timeout

§Parameters
  • dst:[out] destination array
  • timeoutNs: timeout in nanoseconds, -1 for infinite wait
§Returns

true if result is ready, false if the timeout has expired

Note: Result or stored exception can be fetched only once.

source

fn get_with_timeout_f64( &self, dst: &mut impl ToOutputArray, timeout_ns: f64, ) -> Result<bool>

source

fn wait_for(&self, timeout_ns: i64) -> Result<bool>

source

fn wait_for_f64(&self, timeout_ns: f64) -> Result<bool>

source

fn valid(&self) -> bool
