Errors produced by Sassi’s binary wire container.

Sassi values cross runtime and process boundaries inside a fixed binary header followed by a postcard-encoded body. The header captures the wire major, kind discriminator, optional flags, and the cached type name so readers can reject incompatible payloads before touching the body. Postcard’s own error type is intentionally not part of the public surface — its detail is folded into Codec so the wire format can evolve without leaking the codec choice.

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.

VersionMismatch

The wire major is not understood by this crate.

Fields

got: u16

Major version found in the wire header.

expected: u16

Major version this crate can read.

InvalidMagic

The byte stream does not start with Sassi’s wire magic.

KindMismatch

The byte stream is a different Sassi wire kind than the caller expected.

Fields

got: u8

Kind byte found in the wire header.

expected: u8

Kind byte required by the decode path.

UnsupportedKind

The byte stream uses a reserved or unsupported wire kind.

Fields

kind: u8

Reserved or unsupported kind byte.

UnsupportedFlags

The byte stream sets flags this crate does not understand.

Fields

flags: u8

Unsupported flags byte.

TypeNameMismatch

The header names a different cached type.

Fields

got: String

Type name found in the wire header.

expected: &'static str

Type name required by the decode path.

MalformedHeader(String)

The fixed header or variable type-name segment is malformed.

Codec(String)

The postcard body failed to encode or decode.

Trait Implementations

impl Debug for WireFormatError

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

Formats the value using the given formatter.

impl Display for WireFormatError

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

Formats the value using the given formatter.

impl Error for WireFormatError

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.
