A ULE parse / serialize error.

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 shorter than required.

Fields

need: usize

Bytes required.

have: usize

Bytes available.

what: &'static str

What was being parsed.

OutputBufferTooSmall

The output buffer passed to serialize_into was too small.

Fields

need: usize

Bytes required.

have: usize

Bytes available.

InvalidLength

The SNDU Length field is inconsistent with the available bytes.

Length counts from the byte after the Type field up to and including the CRC (RFC 4326 §4.2).

Fields

length: u16

The Length field value.

reason: &'static str

Why it is invalid.

CrcMismatch

The 32-bit CRC trailer did not match the recomputed value (RFC 4326 §4.6).

Fields

computed: u32

CRC recomputed over the SNDU.

found: u32

CRC read from the trailer.

FieldTooWide

A field value did not fit in its wire bit-width.

Fields

what: &'static str

The over-wide field name.

value: u32

The offending value.

bits: u32

The field width on the wire.

InvalidExtensionHeader

An extension header was malformed (bad H-LEN/H-Type or truncated body).

Fields

reason: &'static str

Why the extension header is invalid.

TsMapping

A TS packet payload was the wrong size or carried an invalid Payload Pointer (RFC 4326 §6/§7).

Fields

reason: &'static str

Why the TS payload could not be processed.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

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 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.
