Implements the “Subscribe” algorithm described in the GraphQL specification.
Returns a Promise which resolves to either an AsyncIterator (if successful)
or an ExecutionResult (error). The promise will be rejected if the schema or
other arguments to this function are invalid, or if the resolved event stream
is not an async iterable.
If the client-provided arguments to this function do not result in a
compliant subscription, a GraphQL Response (ExecutionResult) with
descriptive errors and no data will be returned.
If the source stream could not be created due to faulty subscription
resolver logic or underlying systems, the promise will resolve to a single
ExecutionResult containing errors and no data.
If the operation succeeded, the promise resolves to an AsyncIterator, which
yields a stream of ExecutionResults representing the response stream.
Accepts either an object with named arguments, or individual arguments.
