Typed error for the daemon’s wire-codec helpers (encode/decode/ validate). Replaces ad-hoc Result<T, String> in the daemon’s codec surface. Named WireCodecError to avoid shadowing myelon::codec::CodecError (which we import at the top of this file for the typed-transport surface).

Each variant carries enough context to be operator-actionable without grepping the source.

Variants

Truncated

A length prefix or sentinel claimed more bytes than the payload contains.

Fields

what: &'static str

needed: usize

at: usize

got: usize

BadMagic

First N bytes don’t match the expected magic for this op.

Fields

op: &'static str

expected: &'static [u8]

got_len: usize

got: Vec<u8>

LengthOverflow

Length arithmetic would overflow usize.

Fields

what: &'static str

TrailingBytes

Trailing bytes past the parsed end of the payload.

Fields

what: &'static str

extra: usize

BodyLengthMismatch

Body length stated in the prefix doesn’t match the actual payload bytes available.

Fields

what: &'static str

claimed: usize

actual: usize

Utf8

UTF-8 decode failure for a key/string field.

Fields

what: &'static str

source: Utf8Error

Rkyv

rkyv encode/decode failure, scoped by op name.

Fields

op: &'static str

source: Error

SegmentNameBudget(String)

SHM segment-name budget validation failure (see validate_segment_name_budget).

Trait Implementations

impl Debug for WireCodecError

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

Formats the value using the given formatter.

impl Display for WireCodecError

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

Formats the value using the given formatter.

impl Error for WireCodecError

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.
