Trait Implementations

impl<SPI: Clone, CS: Clone> Clone for SPIInterface<SPI, CS> where
    SPI: Transfer<u8>,
    SPI: Write<u8, Error = <SPI as Transfer<u8>>::Error>,
    <SPI as Transfer<u8>>::Error: Debug,
    CS: OutputPin<Error = Infallible>, 

fn clone(&self) -> SPIInterface<SPI, CS>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<SPI: Debug, CS: Debug> Debug for SPIInterface<SPI, CS> where
    SPI: Transfer<u8>,
    SPI: Write<u8, Error = <SPI as Transfer<u8>>::Error>,
    <SPI as Transfer<u8>>::Error: Debug,
    CS: OutputPin<Error = Infallible>, 

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<SPI, CS> Interface for SPIInterface<SPI, CS> where
    SPI: Transfer<u8>,
    SPI: Write<u8, Error = <SPI as Transfer<u8>>::Error>,
    <SPI as Transfer<u8>>::Error: Debug,
    CS: OutputPin<Error = Infallible>, 

type Error = <SPI as Transfer<u8>>::Error

Error specific to the serial link.

fn write(&mut self, frame: &[u8]) -> Result<(), Self::Error>

Writes a frame to the Pn532

fn wait_ready(&mut self) -> Poll<Result<(), Self::Error>>

Checks if the Pn532 has data to be read. Uses either the serial link or the IRQ pin.

fn read(&mut self, buf: &mut [u8]) -> Result<(), Self::Error>

Reads data from the Pn532 into buf. This method will only be called if wait_ready returned Poll::Ready(Ok(())) before.
