Enum embedded_error::SpiError

#[non_exhaustive]pub enum SpiError {
    Overrun,
    ModeFault,
    CRCError,
    FrameFormatError,
    Impl(ImplError),
}

This crate contains a variety of universal error types which can be used to universally model conditions which can typically arise for certain peripherals.

When used by HAL implementations, they allow drivers and applications alike to generically handle those situations without the error handling being specific to the hardware it is supposed to run on (which is usually not possible to implement in drivers).

All of the enums in this crate are marked as #[non_exhaustive] to allow for additions of new error kinds without requiring a breaking change and version bump. A SPI specific error.

This error type contains errors specific to SPI peripherals. Also it has an Impl kind to pass through implementation specific errors occuring while trying to use a SPI peripheral.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Overrun

The peripheral receive buffer was overrun

ModeFault

Multiple devices on the SPI bus are trying across each other, e.g. in a multi-master setup

CRCError

CRC does not match the received data

FrameFormatError

Received data does not conform to the peripheral configuration

Impl(ImplError)

Implementation specific error (shared across all peripheral specific error kinds)
