Variants§

§

Set

Sets the power elements to specific states supported by SAG.

The initial state of SAG is (2, 0, 0, 0). SAG maintains execution_state_level == 2 until a “boot complete” logic is triggered. “boot complete” logic is triggered by setting SAG states to (2, 1, any, any).

Supported states before “boot complete”:

  • (2, any, any, any) Supported states after “boot complete”:
  • (2, 1, any, any)
  • (1, 0, 1, any)
  • (1, 0, any, 1)
  • (0, 0, 0, 0)

In SystemActivityGovernorState, omitting specifying a power element’s state will preserve its existing state.

§

Get

Return immediately with the current state of SAG.

Fields

§

Watch

On a given connection, the first call will return immediately with SAG’s current state. Subsequent Watch requests will only return if and only if a test.sagcontrol.State.Set call sends a request and SAG’s state has changed to the requested supported state.

For example, if the current state of SAG is (1, 0, 1, 0), the first Watch will return (1, 0, 1, 0). If a test.sagcontrol.State.Set call sends a request to change state to (2, 1, 0, 1), the next Watch will return when the SAG’s state has fully transitioned to (2, 1, 0, 1), any intermediate transient state (in this example, (2, 0, 1, 0), (2, 1, 1, 0) and (2, 1, 1, 1)) will not be returned.

Clients should use this to synchronize SAG states.

Fields

§

_UnknownMethod

An interaction was received which does not match any known method.

Fields

This variant is marked as non-exhaustive
Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.
§ordinal: u64

Ordinal of the method that was called.

§control_handle: StateControlHandle
§method_type: MethodType
