Enum A2AError 

#[non_exhaustive]
pub enum A2AError {
    Http(String),
    Parse(String),
    Api {
        code: i32,
        message: String,
    },
    Timeout(String),
    Signature(String),
    InputRequired {

    },
}

Errors that can occur during A2A client operations.

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.

Http(String)

HTTP transport error.

Parse(String)

JSON parse error.

Api

API-level error (returned by the remote agent).

Fields

code: i32

The JSON-RPC error code.

message: String

Human-readable error message.

Timeout(String)

Request timed out.

Signature(String)

Agent card signature verification failed, or a signed card could not be verified (P1-3).

InputRequired

The agent needs more information before it can continue (P2-3).

Resume the conversation with A2AClient::resume_task.

Fields

task_id: String

ID of the task requiring more input.

prompt: String

Prompt describing what additional input is needed.

Trait Implementations

impl Debug for A2AError

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

Formats the value using the given formatter.

impl Display for A2AError

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

Formats the value using the given formatter.

impl Error for A2AError

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<A2AError> for GatewayError

fn from(source: A2AError) -> Self

Converts to this type from the input type.

impl From<A2AErrorData> for A2AError

fn from(err: A2AErrorData) -> Self

Converts to this type from the input type.

impl From<Error> for A2AError

fn from(err: Error) -> Self

Converts to this type from the input type.
