Enum StatefulStreamResult

Source
pub enum StatefulStreamResult<T> {
    Ready(T),
    Continue,
}
Expand description

Represents the result of a stateful operation.

This enumueration indicates whether the state produced a result that is ready for use (Ready) or if the operation requires continuation (Continue).

Variants:

  • Ready(T): Indicates that the operation is complete with a result of type T.
  • Continue: Indicates that the operation is not yet complete and requires further processing or more data. When this variant is returned, it typically means that the current invocation of the state did not produce a final result, and the operation should be invoked again later with more data and possibly with a different state.
