Main error type for the batching system.

Variants

RequestNotFound(RequestId)

Request not found

RequestStateConflict

Request exists but is not in the expected state for the requested operation (e.g., completing an already-completed or failed request).

Distinct from [RequestNotFound] so callers can be properly idempotent against concurrent writers — e.g. a complete-then-complete race where the second caller should treat “already completed” as success rather than synthesizing a new row.

Fields

id: RequestId

current_state: String

expected: &'static str

RequestCancelled(RequestId)

Cancelled request

Shutdown

Daemon is shutting down

InvalidState(RequestId, String, String)

Request is in an invalid state for the requested operation

ValidationError(String)

Validation error (e.g., invalid file format, missing required fields)

HttpClient(String)

HTTP client error.

HttpRequestBuilder(String)

HTTP request builder error.

HttpClientTimeout(String)

HTTP client timeout.

FirstChunkTimeout(String)

Timed out waiting for response headers + first body chunk (time-to-first-token). Only used for streaming requests. Handles servers (like vLLM) that return headers immediately but queue the request before producing tokens.

TokensTimeout(String)

Timed out waiting for the next chunk of response body tokens (streaming only)

BodyTimeout(String)

Timed out waiting for the entire response body to complete (streaming only). Fires when the total body read exceeds body_timeout.

Serialization(Error)

Serialization/deserialization error

Other(Error)

General error from anyhow

Trait Implementations

impl Debug for FusilladeError

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

Formats the value using the given formatter.

impl Display for FusilladeError

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

Formats the value using the given formatter.

impl Error for FusilladeError

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.
