Enum Error

#[non_exhaustive]
pub enum Error {
    TxBufferTooLong,
    RxBufferTooLong,
    Transmit,
    Receive,
    BufferNotInRAM,
    AddressNack,
    DataNack,
    Overrun,
    Timeout,
}

TWI error.

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.

TxBufferTooLong

TX buffer was too long.

RxBufferTooLong

RX buffer was too long.

Transmit

Data transmit failed.

Receive

Data reception failed.

BufferNotInRAM

The buffer is not in data RAM. It’s most likely in flash, and nRF’s DMA cannot access flash.

AddressNack

Didn’t receive an ACK bit after the address byte. Address might be wrong, or the i2c device chip might not be connected properly.

DataNack

Didn’t receive an ACK bit after a data byte.

Overrun

Overrun error.

Timeout

Timeout error.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Error for Error

fn kind(&self) -> ErrorKind

Convert error to a generic I2C error kind.

impl Format for Error

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl PartialEq for Error

fn eq(&self, other: &Error) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
