Error variants that parsers + builders can return.

Spec references inside #[error(...)] strings quote clauses from ITU-T H.222.0 (= ISO/IEC 13818-1) 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.

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.

InvalidSyncByte

TS sync byte was not the expected 0x47.

Fields

found: u8

The byte actually read at position 0.

OutputBufferTooSmall

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

Fields

need: usize

Required size.

have: usize

Actual size.

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.

PayloadTooLarge

A payload was longer than a single TS packet’s fixed payload capacity (see OwnedTsPacket::serialize_with_payload, #1129).

Fields

len: usize

The payload length that did not fit.

max: usize

The maximum payload capacity.

FieldOverflow(FieldOverflow)

A length or count field’s value does not fit its wire field (see broadcast_common::len, #1129).

SectionPayloadLengthMismatch

Section::payload did not match what section_length implies (see Section::serialize_into, #1074 W5). Serializing a hand-built Section whose fields disagree used to index past serialized_len() and panic (or write the CRC over payload bytes) instead of erroring.

Fields

section_length: u16

section_length field the caller set.

expected: usize

Payload length section_length implies (accounting for the extension header + CRC on long-form sections).

actual: usize

Actual payload.len().

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<FieldOverflow> for Error

fn from(source: FieldOverflow) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for Error
