Error variants that parsers + builders can return.

Spec references inside #[error(...)] strings quote clauses from ETSI EN 300 468 v1.19.1 where applicable.

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.

CrcMismatch

CRC-32 validation failed for a table section.

Fields

computed: u32

CRC we calculated over the section bytes.

expected: u32

CRC carried at the end of the section.

UnexpectedTableId

table_id byte doesn’t match any expected value for the parser invoked.

Fields

table_id: u8

Byte value actually read.

what: &'static str

Table names or parser expecting it.

expected: &'static [u8]

The permitted set.

InvalidDescriptor

Descriptor payload failed semantic validation.

Fields

tag: u8

Descriptor tag being parsed.

reason: &'static str

Specific failure reason.

InvalidBcd

BCD-encoded value is out of valid range.

Fields

field: &'static str

Field name where the BCD sits.

bytes: [u8; 4]

The (up to 4) raw bytes inspected.

SectionLengthOverflow

A section_length declared more bytes than the containing buffer could hold.

Fields

declared: usize

Length bytes declared inside the section header.

available: usize

Bytes actually available after the header.

ReservedBitsViolation

A reserved bit was not in the expected state. Most parsers are permissive about reserved bits; this variant is only emitted when a spec clause specifically requires a value.

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.

InvalidSyncByte

TS sync byte was not the expected 0x47.

Fields

found: u8

The byte actually read at position 0.

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 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.
