Errors produced by TLV decoding.

Variants

UnexpectedEof

Packet was truncated before the expected end.

UnknownCriticalType(u64)

Unknown TLV type with the critical bit set (odd type number) — must drop.

InvalidLength

A field had the wrong encoded length.

Fields

typ: u64

expected: usize

got: usize

InvalidUtf8

A UTF-8 field contained invalid bytes.

Fields

typ: u64

MissingField(&'static str)

A required field was absent.

DuplicateField(u64)

The same TLV type appeared more than once where only one is allowed.

NonMinimalVarNumber

VarNumber is not in shortest encoding form.

Trait Implementations

impl Clone for TlvError

fn clone(&self) -> TlvError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TlvError

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

Formats the value using the given formatter.

impl Display for TlvError

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

Formats the value using the given formatter.

impl Error for TlvError

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 TlvError

fn eq(&self, other: &TlvError) -> 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.
