Struct EmptyTransport

pub struct EmptyTransport;

An EmptyTransport provides no communications backend.

Trait Implementations

impl Transport for EmptyTransport

fn capabilities(&self) -> Result<Capabilities>

Returns a Capabilities object to check the capabilities of this transport object.

fn apply_default_configuration(&self) -> Result<()>

Resets the transport to power-on condition. That is, pin/uart/spi configuration reverts to default, ongoing operations are cancelled, etc.

fn jtag(&self, _opts: &JtagParams) -> Result<Box<dyn JtagChain + '_>>

Returns a JtagChain implementation.

fn spi(&self, _instance: &str) -> Result<Rc<dyn Target>>

Returns a SPI Target implementation.

fn i2c(&self, _instance: &str) -> Result<Rc<dyn Bus>>

Returns a I2C Bus implementation.

fn uart(&self, _instance: &str) -> Result<Rc<dyn Uart>>

Returns a Uart implementation.

fn gpio_pin(&self, _instance: &str) -> Result<Rc<dyn GpioPin>>

Returns a GpioPin implementation.

fn gpio_monitoring(&self) -> Result<Rc<dyn GpioMonitoring>>

Returns a GpioMonitoring implementation, for logic analyzer functionality.

fn gpio_bitbanging(&self) -> Result<Rc<dyn GpioBitbanging>>

Returns a GpioBitbanging implementation, for timed and synchronized manipulation of multiple GPIO pins.

fn emulator(&self) -> Result<&dyn Emulator>

Returns a Emulator implementation.

fn fpga_ops(&self) -> Result<&dyn FpgaOps>

Methods available only on FPGA implementations.

fn proxy_ops(&self) -> Result<&dyn ProxyOps>

Methods available only on Proxy implementation.

fn dispatch(&self, _action: &dyn Any) -> Result<Option<Box<dyn Serialize>>>

Invoke non-standard functionality of some Transport implementations.

fn relinquish_exclusive_access( &self, callback: Box<dyn FnOnce() + '_>, ) -> Result<()>

Invoke the provided callback (preferably) without exclusive access.
