Struct ControllerProxy 

pub struct ControllerProxy { /* private fields */ }

Implementations

impl ControllerProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.hardware.power.charger/Controller.

pub fn take_event_stream(&self) -> ControllerEventStream

Get a Stream of events from the remote end of the protocol.

Panics

Panics if the event stream was already taken.

pub fn set_control( &self, options: &ControlOptions, ) -> QueryResponseFut<ControllerSetControlResult, DefaultFuchsiaResourceDialect>

Applies operational and electrical constraints to the charger converter.

Validation is atomic: a request rejected with NOT_SUPPORTED or INVALID_ARGS leaves hardware and session state untouched. The response is returned only after all corresponding hardware register writes have completed and been acknowledged by the charger IC.

Parameters:

• options: The constraints to apply. Present fields overwrite the constraints previously set on this connection for those fields; omitted fields leave this connection’s prior constraints for those fields unchanged.

Errors:

• NOT_SUPPORTED: One or more requested constraints are not adjustable on this hardware/arbiter, or the requested operating_mode is absent from Spec.supported_modes.
• INVALID_ARGS: A requested value is outside the range the hardware can program, or the requested operating_mode conflicts with the active power path state (for example, requesting OperatingMode::OTG while external input power is online on the same port).
• IO: Communication failure with the charger hardware (e.g. SPMI transfer failure).
• INTERNAL: Internal driver error.

pub fn clear_control( &self, options: &ControlOptions, ) -> QueryResponseFut<ControllerClearControlResult, DefaultFuchsiaResourceDialect>

Withdraws constraints applied through this connection for the fields present in options.

options acts as a field mask: only field presence (set vs. unset) is inspected, and the field values themselves are ignored.

• If options is empty (no fields set), all constraints applied through this connection are withdrawn.
• If one or more fields are set in options, only the constraints corresponding to those fields are withdrawn, leaving any other fields untouched.

Each cleared field reverts to the next active constraint, if any, or otherwise to the autonomous hardware / board-configured default that [Controller] restores on close. Succeeds without effect for any targeted field that is not currently constrained.

Parameters:

• options: Mask of ControlOptions fields whose constraints should be withdrawn, or an empty table to withdraw all constraints on this connection.

Errors:

• IO: Communication failure with the charger hardware. Fields that could not be reverted retain their constraint, so the call can be retried.
• INTERNAL: Internal driver error.
