Variants

A2A(A2AError)

Http(Error)

Json(Error)

InvalidInput(String)

ReadFile

Fields

path: String

source: Error

Timeout

Fields

task_id: String

timeout: Duration

CardFile

A local Agent Card file that couldn’t be read — the file-path counterpart of a non-2xx card fetch.

Fields

path: String

source: Error

CardInvalid(String)

A local Agent Card file that was read but isn’t an Agent Card — the counterpart of a response body that won’t deserialize.

CardSchemaInvalid

card get --validate: the card deserialized fine (so CardInvalid does not apply) but fails the A2A JSON schema (§10.1) — distinct from a type-check failure, and carrying every violation rather than only the first.

Fields

violations: Vec<Violation>

Usage(String)

A malformed invocation, as clap describes it. §11.4 counts a malformed flag among the CLI-local failures that must still be machine-readable, so clap’s prose becomes the envelope’s message rather than being printed in its place.

Implementations

impl CliError

pub fn exit_code(&self) -> i32

The exit status this failure maps to (§11.6, Appendix D). 0 is never returned here — success never constructs a CliError.

pub fn report(&self)

Print the Appendix B error envelope to stderr as one compact JSON line, in every output mode: §11.4 requires errors to be machine-readable unconditionally, not only under -o json.

Trait Implementations

impl Debug for CliError

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

Formats the value using the given formatter.

impl Display for CliError

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

Formats the value using the given formatter.

impl Error for CliError

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.
