Enum DeserializeError 

#[non_exhaustive]
pub enum DeserializeError {
    SchemaVersionMismatch {
        expected: u32,
        got: u32,
    },
    PayloadMalformed,
    UnknownTypeCode {
        observed: TypeCode,
    },
    LengthExceedsBudget,
}

Deserialization failure for canonical-bytes round-trip.

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.

SchemaVersionMismatch

Stored bytes carry a different SCHEMA_VERSION than the type being decoded into.

Fields

expected: u32

SCHEMA_VERSION declared on the target type.

got: u32

version argument supplied by the caller.

PayloadMalformed

Postcard refused to decode the bytes (truncated, invalid tag, type-shape mismatch).

UnknownTypeCode

TypeCode not present in the registry consulted at decode time.

Fields

observed: TypeCode

The unrecognized TypeCode.

LengthExceedsBudget

Encoded length exceeded the configured per-Action / per-Component byte budget.

Trait Implementations

impl Clone for DeserializeError

fn clone(&self) -> DeserializeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeserializeError

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

Formats the value using the given formatter.

impl Display for DeserializeError

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

Formats the value using the given formatter.

impl Error for DeserializeError

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.
