Why a compact encode or decode failed.

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.

UnknownSchema(SchemaId)

A referenced schema id is not in the registry (r[schema-identity.unknown-is-error]).

BundleSchemaIdMismatch

A received schema bundle member’s stated id did not match its content hash.

Fields

stated: SchemaId

recomputed: SchemaId

Unsupported(&'static str)

A kind or feature not yet implemented in this codec.

TypeMismatch

The value’s shape does not match the schema it is being encoded against.

Fields

expected: &'static str

UnknownVariant(String)

An enum value names a variant the schema does not have.

BadVariantIndex(u32)

A decoded enum variant index is out of range.

GenericArity

A generic schema applied with the wrong number of type arguments.

Fields

params: usize

args: usize

Malformed(&'static str)

A structurally malformed schema (e.g. an unbound type variable, or a primitive carrying type arguments).

Incompatible(String)

Two schemas cannot be translated by a compatibility plan (r[compat.*]).

WriterOnlyVariant(u32)

A decoded enum variant exists in the writer schema but has no counterpart in the reader schema (r[compat.enum]).

Decode(DecodeError)

A decode-side validation failure from the byte reader.

Encode(EncodeError)

A dynamic (self-describing) sub-value failed to encode.

Trait Implementations

impl Clone for CompactError

fn clone(&self) -> CompactError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompactError

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

Formats the value using the given formatter.

impl Display for CompactError

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

Formats the value using the given formatter.

impl Eq for CompactError

impl Error for CompactError

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<DecodeError> for CompactError

fn from(e: DecodeError) -> Self

Converts to this type from the input type.

impl From<EncodeError> for CompactError

fn from(e: EncodeError) -> Self

Converts to this type from the input type.

impl PartialEq for CompactError

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