Enum CapabilityError 

pub enum CapabilityError {
    Unavailable(String),
    InvalidInput(String),
    ExecutionFailed(String),
}

Errors that can occur when interacting with capabilities.

This enum is used as the error type across all capability traits (Invocable, ResourceProvider, PromptProvider).

Variants

Unavailable(String)

The requested capability, resource, or prompt is not available.

Returned when the identifier does not match any registered item or when the provider is temporarily offline.

InvalidInput(String)

The input provided to the capability is invalid.

Returned when the model-supplied arguments fail schema validation or contain values outside the expected domain.

ExecutionFailed(String)

The capability encountered an error during execution.

Returned for runtime failures such as network timeouts, I/O errors, or unexpected backend responses.

Trait Implementations

impl Debug for CapabilityError

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

Formats the value using the given formatter.

impl Display for CapabilityError

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

Formats the value using the given formatter.

impl Error for CapabilityError

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>)
