Errors returned by the DExtra codec functions.

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.

UnknownPacketLength

DExtra packet length is not one of the known sizes.

Fields

got: usize

Observed length.

DsvtMagicMissing

Packet expected to be DSVT-framed but the magic at [0..4] is wrong.

Fields

got: [u8; 4]

Observed bytes.

StreamIdZero

Stream id at offsets [12..14] is zero.

InvalidModuleByte

LINK packet has a non-A-Z reflector or client module byte.

Fields

offset: usize

Byte offset within the 11-byte packet.

byte: u8

Rejected byte.

UnknownConnectTag

Connect reply tag at [10..13] is neither ACK nor NAK.

Fields

tag: [u8; 3]

The 3-byte tag observed.

EncodeBufferTooSmall

An encoder was called with an undersized output buffer.

Programming error inside crate::session::client::SessionCore; surfaced as a variant rather than swallowed so callers can still observe the fault.

Fields

need: usize

How many bytes the encoder needed.

have: usize

How many bytes the buffer actually held.

Trait Implementations

impl Clone for DExtraError

fn clone(&self) -> DExtraError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DExtraError

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

Formats the value using the given formatter.

impl Display for DExtraError

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

Formats the value using the given formatter.

impl Error for DExtraError

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<DExtraError> for ProtocolError

fn from(source: DExtraCodecError) -> Self

Converts to this type from the input type.

impl From<EncodeError> for DExtraError

fn from(value: EncodeError) -> Self

Converts to this type from the input type.

impl PartialEq for DExtraError

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