Enum Error

pub enum Error<SPI: Transfer<u8>, GPIO: OutputPin> {
    Spi(SPI::Error),
    Gpio(GPIO::Error),
    UnexpectedStatus,
    // some variants omitted
}

The error type used by this library.

This can encapsulate an SPI or GPIO error, and adds its own protocol errors on top of that.

Variants

Spi(SPI::Error)

An SPI transfer failed.

Gpio(GPIO::Error)

A GPIO could not be set.

UnexpectedStatus

Status register contained unexpected flags.

This can happen when the chip is faulty, incorrectly connected, or the driver wasn’t constructed or destructed properly (eg. while there is still a write in progress).

Trait Implementations
