Error produced while constructing, encoding, or decoding a long frame.

Variants

IncompleteHeader

Fewer than four header bytes were supplied.

Fields

actual: usize

InvalidLength

The encoded length differed from that declared by the frame.

Fields

expected: usize

actual: usize

InvalidStart

A start byte was invalid.

Fields

index: usize

actual: u8

MismatchedDataLengths

The repeated length fields differed.

Fields

first: u8

second: u8

InvalidDataLength

The length field did not leave room for user data.

Fields

actual: u8

InvalidStop

The stop byte was invalid.

Fields

actual: u8

InvalidChecksum

The checksum did not match the frame contents.

Fields

expected: u8

actual: u8

Control(ControlError)

The control field is invalid for a variable-format frame.

InvalidUserDataLength

User data was empty or exceeded 252 bytes.

Fields

actual: usize

OutputTooSmall

The output buffer was too small.

Fields

Performs copy-assignment from source.

impl Copy for LongFrameError

impl Debug for LongFrameError

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

Formats the value using the given formatter.

impl Eq for LongFrameError

impl Error for LongFrameError

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl PartialEq for LongFrameError

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

Equality operator ==.

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

Inequality operator !=.
