@spec asyncArray() :: t() | {:error, String.t()}

AsyncArray

Return

• self: Evision.AsyncArray

Python prototype (for reference only):

AsyncArray() -> <AsyncArray object>

@spec get(t()) :: Evision.Mat.t() | {:error, String.t()}

get

Positional Arguments

• self: Evision.AsyncArray.t()

Return

• dst: Evision.Mat.

  destination array

Fetch the result.

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.

Python prototype (for reference only):

get([, dst]) -> dst

@spec get(t(), [{atom(), term()}, ...] | nil) ::
  Evision.Mat.t() | {:error, String.t()}

@spec get(t(), number()) :: Evision.Mat.t() | false | {:error, String.t()}

Variant 1:

get

Positional Arguments

• self: Evision.AsyncArray.t()

• timeoutNs: double.

  timeout in nanoseconds, -1 for infinite wait

Return

• retval: bool

• dst: Evision.Mat.

  destination array

Retrieving the result with timeout

@returns true if result is ready, false if the timeout has expired Note: Result or stored exception can be fetched only once.

Python prototype (for reference only):

get(timeoutNs[, dst]) -> retval, dst
