Errors that can occur while decoding (unpacking) a value from wire format.

Variants

UnexpectedEof

The input ended before all expected fields were read.

InvalidUtf8

A string field contained bytes that are not valid UTF-8.

InvalidVarint

A LEB128 varint was too long or used an overlong encoding.

LimitExceeded

A decoded length or count exceeded its safety limit.

Fields

field: &'static str

limit: u64

actual: u64

UnknownEnumVariant

The discriminant for an enum did not match any known variant.

Fields

type_name: &'static str

value: u64

UnknownUnionVariant

The discriminant for a union did not match any known variant.

Fields

type_name: &'static str

discriminant: u64

RemovedField

A field that was marked as removed in the schema was encountered.

Fields

ordinal: u16

removed_in: &'static str

reason: &'static str

InvalidValue

A field value was syntactically valid but semantically invalid.

Fields

field: &'static str

message: String

RecursionLimitExceeded

Recursive type nesting exceeded MAX_RECURSION_DEPTH.

SchemaMismatch

The BLAKE3 schema hash in the data did not match the local schema.

Fields

local: [u8; 32]

remote: [u8; 32]

Trait Implementations

impl Clone for DecodeError

fn clone(&self) -> DecodeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Error for DecodeError

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 DecodeError

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