Enum RpcClientError 

#[non_exhaustive]
pub enum RpcClientError {
    Transport(TransportError),
    Codec(CratestackError),
    InvalidResponse(String),
    BadInput(String),
    Envelope(EnvelopeError),
    Remote(RpcRemoteError),
}

Top-level error returned by the RPC client. Mirrors ClientError (the REST error type) but reports server-side failures as RpcRemoteError { code, message, details } rather than the REST-shaped CratestackErrorResponse.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Transport(TransportError)

Codec(CratestackError)

InvalidResponse(String)

BadInput(String)

Envelope(EnvelopeError)

The signed transport failed (cratestack#1007).

Remote(RpcRemoteError)

Implementations

impl RpcClientError

pub fn remote(&self) -> Option<&RpcRemoteError>

The server’s answer, for an RpcClientError::Remote.

pub fn challenges(&self) -> &[String]

The WWW-Authenticate values of an RpcClientError::Remote, raw and in order; empty for any other variant.

impl RpcClientError

pub fn step_up(&self) -> Option<StepUpRequired>

The step-up refusal of an RpcClientError::Remote; None for any other variant.

Trait Implementations

impl Debug for RpcClientError

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

Formats the value using the given formatter.

impl Display for RpcClientError

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

Formats the value using the given formatter.

impl Error for RpcClientError

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.
