dir: OpKind

Implementations

impl I2cError

pub fn new(addr: Addr, kind: ErrorKind, dir: OpKind) -> Self

Constructs a new I2cError from an embedded_hal_async::i2c::ErrorKind.

This method is intended to be used by implementations of the I2cService when they encounter an error performing an I²C operation.

pub fn operation(&self) -> OpKind

Returns whether this error occurred while performing an I²C read or write operation.

pub fn is_user_error(&self) -> bool

Returns true if this I2cError represents an invalid use of the I2cClient/Transaction APIs.

User errors include:

• Attempting to read or write after performing a read or write operation with end: true, ending the transaction.
• Attempting to read or write with a buffer that is too small for the desired read/write operation.
