Errors surfaced by the wire encoder/decoder.

Variants

FrameTooLarge

Frame body exceeded MAX_FRAME_BODY_BYTES.

Fields

len: usize

Length of the offending frame body, in bytes.

FrameTruncated

Frame body shorter than the declared length prefix.

Fields

declared: u32

Length declared by the 4-byte big-endian length prefix.

actual: usize

Actual number of body bytes available after the header.

ShortHeader

Length-prefix header itself is shorter than 4 bytes.

Fields

got: usize

Number of header bytes actually received.

UnexpectedEof

CBOR ran past end of buffer.

UnsupportedMajor

CBOR major type is not in the supported subset (0, 3, 5).

Fields

major: u8

Offending CBOR major type encountered in the buffer.

UnsupportedAdditional

CBOR additional info encodes indefinite-length or > 8-byte length.

Fields

additional: u8

Offending CBOR additional-info nibble (0..=31).

NotMap5

Outer item is not a 5-entry definite map.

ContentVersionMustBeFirst

First map key is not the literal text "content_version" — host short-circuits unknown majors before walking the rest.

UnsupportedContentVersion(u16)

content_version major is not WIRE_CONTENT_VERSION_MAJOR.

MissingField(&'static str)

Required field missing or duplicated.

FieldType

Field present but wrong CBOR major.

Fields

field: &'static str

Name of the field whose CBOR major did not match the schema.

got_major: u8

CBOR major type actually observed for that field.

IntegerOverflow

Integer field overflowed its declared width.

Fields

field: &'static str

Name of the integer field that exceeded its declared width.

UnknownProbeSource(String)

Probe-source string not in probe_source::ALL.

InvalidUtf8

Text field is not valid UTF-8.

Fields

field: &'static str

Name of the text field that failed UTF-8 validation.

Trait Implementations

impl Clone for WireError

fn clone(&self) -> WireError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WireError

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

Formats the value using the given formatter.

impl Display for WireError

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

Formats the value using the given formatter.

impl Error for WireError

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 WireError

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