Trait Implementations

impl<M: Debug + Middleware> Debug for DevRpcMiddlewareError<M>

where M::Error: Debug,

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

Formats the value using the given formatter.

impl<M: Middleware> Display for DevRpcMiddlewareError<M>

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

Formats the value using the given formatter.

impl<M: Middleware> Error for DevRpcMiddlewareError<M>

where Self: Debug + Display,

fn source(&self) -> Option<&(dyn Error + 'static)>

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<M> From<ProviderError> for DevRpcMiddlewareError<M>

where M: Middleware,

fn from(src: ProviderError) -> Self

Converts to this type from the input type.

impl<M: Middleware> MiddlewareError for DevRpcMiddlewareError<M>

type Inner = <M as Middleware>::Error

The Inner type is the next lower middleware layer’s error type.

fn from_err(src: M::Error) -> DevRpcMiddlewareError<M>

Convert the next lower middleware layer’s error to this layer’s error

fn as_inner(&self) -> Option<&Self::Inner>

Attempt to convert this error to the next lower middleware’s error. Conversion fails if the error is not from an inner layer (i.e. the error originates at this middleware layer)

fn is_inner(&self) -> bool

Returns true if the underlying error stems from a lower middleware layer

fn as_serde_error(&self) -> Option<&Error>

Access an underlying serde_json error (if any)

fn is_serde_error(&self) -> bool

Returns true if the underlying error is a serde_json (de)serialization error. This method can be used to identify

fn as_provider_error(&self) -> Option<&ProviderError>

Attempts to access an underlying ProviderError, usually by traversing the entire middleware stack. Access fails if the underlying error is not a ProviderError

fn from_provider_err(p: ProviderError) -> Self

Convert a ProviderError to this type, by successively wrapping it in the error types of all lower middleware

fn as_error_response(&self) -> Option<&JsonRpcError>

Access an underlying JSON-RPC error (if any)

fn is_error_response(&self) -> bool

Returns true if the underlying error is a JSON-RPC error response
