Function backpressure_set 

pub fn backpressure_set(enabled: bool)

👎Deprecated: use backpressure_{inc,dec} instead

Available on crate feature async only.

Call the backpressure.set canonical built-in function.

When enabled is true, this tells the host to defer any new calls to this component instance until further notice (i.e. until backpressure.set is called again with enabled set to false).
