Enum CodecError 

pub enum CodecError {
    DecodeFailed {
        task_id: String,
        expected_type: &'static str,
        source: BoxError,
    },
    EncodeFailed {
        task_id: String,
        source: BoxError,
    },
}

Errors produced when encoding or decoding task inputs/outputs.

These typed errors carry the task ID and expected type, enabling the runtime (and future “cascade re-execution”) to distinguish schema-mismatch failures from task logic errors.

Variants

DecodeFailed

Failed to decode a task’s input (or a loop/branch envelope).

Fields

task_id: String

The task whose input could not be decoded.

expected_type: &'static str

The Rust type name that was expected (via std::any::type_name).

source: BoxError

The underlying deserialization error.

EncodeFailed

Failed to encode a task’s output.

Fields

task_id: String

The task whose output could not be encoded.

source: BoxError

The underlying serialization error.

Trait Implementations

impl Debug for CodecError

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

Formats the value using the given formatter.

impl Display for CodecError

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

Formats the value using the given formatter.

impl Error for CodecError

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.
