Errors from toolkit operations.

Maps to existing ErrorCode variants in MCP responses (AD-10). Stateless checks live here; stateful checks in the workflow layer (AD-12).

Variants

XApi(XApiError)

Underlying X API error (passthrough).

InvalidInput

Invalid input parameter.

Fields

message: String

TweetTooLong

Tweet text exceeds the maximum length.

Fields

length: usize

max: usize

UnsupportedMediaType

File extension does not map to a supported media type.

Fields

path: String

MediaTooLarge

Media data exceeds the size limit for its type.

Fields

size: u64

max: u64

media_type: String

ThreadPartialFailure

Thread posting failed partway through.

Fields

posted_ids: Vec<String>

IDs of tweets successfully posted before the failure.

failed_index: usize

Zero-based index of the tweet that failed.

posted: usize

Count of successfully posted tweets.

total: usize

Total tweets in the thread.

source: Box<XApiError>

The underlying X API error.

Trait Implementations

impl Debug for ToolkitError

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

Formats the value using the given formatter.

impl Display for ToolkitError

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

Formats the value using the given formatter.

impl Error for ToolkitError

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<ToolkitError> for WorkflowError

fn from(source: ToolkitError) -> Self

Converts to this type from the input type.

impl From<XApiError> for ToolkitError

fn from(source: XApiError) -> Self

Converts to this type from the input type.
