Types

func (*HostedmodelsPredictCall) Context

Context sets the context to be used in this call's Do method. Any pending HTTP request will be aborted if the provided context is canceled.

func (*HostedmodelsPredictCall) Do

func (c *HostedmodelsPredictCall) Do() (*Output, error)

Do executes the "prediction.hostedmodels.predict" call. Exactly one of *Output or error will be non-nil. Any non-2xx status code is an error.
