Struct GpioSynchronousProxy 

pub struct GpioSynchronousProxy { /* private fields */ }

Implementations

impl GpioSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<GpioEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

pub fn read( &self, ___deadline: MonotonicInstant, ) -> Result<GpioReadResult, Error>

Reads the current value of a GPIO, returning true for a high voltage and false for a low voltage.

pub fn set_buffer_mode( &self, mode: BufferMode, ___deadline: MonotonicInstant, ) -> Result<GpioSetBufferModeResult, Error>

Configures the output buffer as per mode.

pub fn get_interrupt( &self, options: InterruptOptions, ___deadline: MonotonicInstant, ) -> Result<GpioGetInterruptResult, Error>

Gets an interrupt object pertaining to a particular GPIO pin. Only one interrupt may be outstanding per pin, and it must be released by calling ReleaseInterrupt() before the next call to GetInterrupt() will succeed. The interrupt is unmasked prior to being returned to the caller.

Returns ZX_ERR_ALREADY_EXISTS if GetInterrupt() has already been called without a subsequent call to ReleaseInterrupt(), ZX_ERR_INVALID_ARGS if options is invalid, or ZX_ERR_ACCESS_DENIED if another client has the interrupt.

pub fn configure_interrupt( &self, config: &InterruptConfiguration, ___deadline: MonotonicInstant, ) -> Result<GpioConfigureInterruptResult, Error>

Configures the polarity of an interrupt and whether it is edge- or level-triggered. Only the client with the interrupt can call ConfigureInterrupt(), unless no client has an interrupt.

Returns ZX_ERR_INVALID_ARGS if no fields are set in config, or ZX_ERR_ACCESS_DENIED if another client has the interrupt.

pub fn release_interrupt( &self, ___deadline: MonotonicInstant, ) -> Result<GpioReleaseInterruptResult, Error>

Releases the interrupt, allowing GetInterrupt() to be called again or by another client. A client’s interrupt is automatically released when it disconnects from the server. The interrupt is masked upon release.

Returns ZX_ERR_NOT_FOUND if the interrupt has already been released, or if GetInterrupt() has not been called. Returns ZX_ERR_ACCESS_DENIED if another client has the interrupt.
