Enum AteccError 

pub enum AteccError<HalError>
where
    HalError: Debug,
{
    Hal(HalError),
    WakeFailed,
    SelfTestFailure,
    BadCrc,
    Chip(ChipError),
    Timeout,
    MalformedResponse,
    BufferTooSmall,
}

Error returned by every public method of crate::Atecc.

Variants

Hal(HalError)

The HAL itself reported an error (I2C bus, GPIO, etc).

WakeFailed

The wake response did not match 04 11 33 43. The chip is either unpowered, miswired, or in self-test failure mode.

SelfTestFailure

The chip returned the self-test-failure pattern 04 07 C4 40 after wake. Hardware is unusable until power-cycle.

BadCrc

CRC-16 of a received frame did not match. The frame is discarded. The caller may retry.

Chip(ChipError)

The chip returned a 4-byte status frame indicating an error.

Timeout

Polling for a command response exceeded the watchdog window (~1.3 s nominal, 2.5 s upper bound).

MalformedResponse

A received frame has an inconsistent length byte.

BufferTooSmall

A caller-supplied buffer is too small for the response.

Implementations

impl<HalError> AteccError<HalError>

where HalError: Debug,

pub fn kind(&self) -> AteccErrorKind

Project this error onto its non-generic AteccErrorKind.

Useful for layers that must report the error over a wire format without leaking the concrete HalError type. The returned value preserves the variant identity and, for AteccError::Chip, the inner ChipError.

Trait Implementations

impl<HalError> Debug for AteccError<HalError>

where HalError: Debug + Debug,

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

Formats the value using the given formatter.

impl<HalError> From<HalError> for AteccError<HalError>

where HalError: Debug,

fn from(err: HalError) -> Self

Converts to this type from the input type.
