        name: String,

    LocalFeatureNotCompiled,

}

Errors a SummarizerService raises. Wraps BackendError with the originating backend’s name so MCP responses can identify the failing backend in summarizer_fallback.from.

Implementations

impl SummarizerError

pub fn from_backend(name: &str, e: BackendError) -> Self

Convert a BackendError into a SummarizerError carrying the originating backend’s name.

pub fn fallback_reason(&self) -> &'static str

Short, stable reason string for summarizer_fallback.reason metadata.

Only meaningful for variants produced by Self::from_backend (i.e. the five mapped from BackendError). Storage/Tokenizer/ NoSuchBackend/NoExtractiveBackendForFallback errors don’t flow through the fallback path and should never reach this method.

Trait Implementations

impl Debug for SummarizerError

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

Formats the value using the given formatter.

impl Display for SummarizerError

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

Formats the value using the given formatter.

impl Error for SummarizerError

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<SummarizerError> for McpError

fn from(source: SummarizerError) -> Self
