Errors related to reading/writing Frames of data.

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.

DataTooLong

Data length exceeded the maximum of 255 bytes.

Fields of DataTooLong

max: u8

The maximum data length.

actual: usize

The actual length of the data that was provided.

Io

Failed reading/writing a Frame of data.

Fields of Io

source: Error

The underlying I/O error.

InvalidFrame

Failed to parse data into a Frame.

Fields of InvalidFrame

data: Vec<u8>

The invalid frame data.

FrameDataMismatch

Frame data didn’t match declared length.

Fields of FrameDataMismatch

data: Vec<u8>

The invalid frame data.

expected: usize

The expected data length.

actual: usize

The actual value of the data that was provided.

BadChecksum

Frame checksum didn’t match declared checksum.

Fields of BadChecksum

data: Vec<u8>

The invalid frame data.

expected: u8

The expected checksum.

actual: u8

The actual checksum of the data.

Trait Implementations

impl Debug for FrameError

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

Formats the value using the given formatter.

impl Display for FrameError

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

Formats the value using the given formatter.

impl Error for FrameError

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

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Error> for FrameError

fn from(source: Error) -> Self

Performs the conversion.
