Error variants that parsers + builders can return.

Spec references inside #[error(...)] strings quote clauses from ETSI TS 102 773 v1.4.1 where applicable.

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.

BufferTooShort

Input buffer was shorter than the smallest valid encoding for the type.

Fields

need: usize

Bytes required to proceed.

have: usize

Bytes actually available.

what: &'static str

Human-readable name of the type or field being parsed.

InvalidPacketType

packet_type byte is not in Table 1 (0x00..=0x02, 0x10..=0x12, 0x20..=0x21, 0x30..=0x33).

Fields

found: u8

Byte value actually read.

ReservedBitsViolation

A reserved bit was not in the expected state.

Fields

field: &'static str

Where.

reason: &'static str

Why.

OutputBufferTooSmall

Write buffer passed to serialize_into was smaller than serialized_len().

Fields

need: usize

Required size.

have: usize

Actual size.

PayloadLengthMismatch

Payload length declared more bits than remaining bytes.

Fields

declared_bits: u16

Declared payload_len_bits from header.

remaining_bytes: usize

Actual remaining bytes.

CrcMismatch

CRC-32 validation failed.

Fields

computed: u32

CRC we calculated over the payload bytes.

expected: u32

CRC carried at the end of the packet.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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 From<TryFromPrimitiveError<Bandwidth>> for Error

fn from(_: TryFromPrimitiveError<Bandwidth>) -> Self

Converts to this type from the input type.

impl From<TryFromPrimitiveError<FrequencySource>> for Error

fn from(_: TryFromPrimitiveError<FrequencySource>) -> Self

Converts to this type from the input type.

impl From<TryFromPrimitiveError<PacketType>> for Error

fn from(e: TryFromPrimitiveError<PacketType>) -> Self

Converts to this type from the input type.

impl From<TryFromPrimitiveError<S1Field>> for Error

fn from(_: TryFromPrimitiveError<S1Field>) -> Self

Converts to this type from the input type.

impl From<TryFromPrimitiveError<SubpartVariety>> for Error

fn from(_: TryFromPrimitiveError<SubpartVariety>) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
