Enum I2cError 

pub enum I2cError {
    Abort,
    ArbitrationLoss,
    InvalidBufferLength,
    AddressOutOfRange,
    UnsupportedTransaction,
    Other,
}

Error returned by I2C operations.

Example

use xpanse_api::bus::i2c::{I2cBusHandle, I2cError};

async fn read_register(bus: &mut I2cBusHandle, dev: u8, reg: u8) -> Result<u8, I2cError> {
    let mut buf = [0u8; 1];
    bus.write_read(dev, &[reg], &mut buf).await?;
    Ok(buf[0])
}

Variants

Abort

ArbitrationLoss

InvalidBufferLength

AddressOutOfRange

UnsupportedTransaction

Other

Any other error reported by the underlying backend.

Trait Implementations

impl Eq for I2cError

impl Error for I2cError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
