Error type for BBFrame parsing and serialization.

All variants carry spec-clause references in their display messages.

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.

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.

InvalidMode

MODE field is neither 0 (NM) nor 1 (HEM).

Fields

mode: u8

MODE value that was rejected.

UnsupportedTsGs

TS/GS input stream type is not supported.

Fields

ts_gs: u8

The invalid TS/GS value.

OutputBufferTooSmall

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

Fields

need: usize

Required size.

have: usize

Actual size.

InvalidIssyForm

ISSY form/prefix bit does not match the decoder called.

Fields

reason: &'static str

Why the form was rejected.

DflOutOfRange

DFL field is outside the valid range. The enforced ceiling DFL_MAX_BITS (64800) is the DVB-S2 normal-FECFRAME data-field bound (EN 302 307-1 §5.1.4); DVB-T2 is tighter still (0..=53760, EN 302 755 Table 2).

Fields

dfl: u16

DFL value that was rejected.

max: u16

Maximum allowed DFL.

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<Mode>> for Error

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

Converts to this type from the input type.

impl From<TryFromPrimitiveError<TsGs>> for Error

fn from(e: TryFromPrimitiveError<TsGs>) -> 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.
