Enum FoldQueryClientError 

pub enum FoldQueryClientError {
    Transport(RpcError),
    Codec(String),
    Server(FoldQueryError),
}

Client-side errors the typed surface produces. Distinct from RpcError (transport) and FoldQueryError (handler-level) so the caller can match on the failure shape they care about.

Variants

Transport(RpcError)

Transport-level failure — no route, timeout, server returned a non-Ok status before invoking the handler.

Codec(String)

Request serialization or response deserialization failed.

Server(FoldQueryError)

Aggregator handler rejected the request (e.g. unknown fold kind). Forwarded from super::FoldQueryResponse::Error.

Trait Implementations

impl Debug for FoldQueryClientError

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

Formats the value using the given formatter.

impl Display for FoldQueryClientError

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

Formats the value using the given formatter.

impl Error for FoldQueryClientError

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.
