Enum TransportError 

pub enum TransportError {
    Http(String),
    WebSocket(String),
    Rpc(JsonRpcError),
    RateLimited {
        provider: String,
    },
    CircuitOpen {
        provider: String,

    Deserialization(Error),
    Overloaded {

    Cancelled,
    Other(String),
}

Errors that can occur during an RPC transport operation.

Variants

Http(String)

HTTP request failed (connection refused, timeout, etc.).

WebSocket(String)

WebSocket connection/send/receive error.

Rpc(JsonRpcError)

JSON-RPC protocol-level error returned by the node.

RateLimited

Rate limit exceeded — caller should back off.

Fields

provider: String

CircuitOpen

Circuit breaker is open — provider is unhealthy.

Fields

provider: String

AllProvidersDown

All providers in the pool are unavailable.

Timeout

Request timed out after the configured duration.

Fields

ms: u64

Deserialization(Error)

Response could not be deserialized.

Overloaded

Request rejected due to backpressure — too many in-flight requests.

Fields

queue_depth: usize

Cancelled

Operation was cancelled via cancellation token.

Other(String)

An unexpected error.

Implementations

impl TransportError

pub fn is_retryable(&self) -> bool

Returns true if this error is retryable (transient).

pub fn is_execution_error(&self) -> bool

Returns true if this is a node-side execution error (not retryable).

Trait Implementations

impl Debug for TransportError

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

Formats the value using the given formatter.

impl Display for TransportError

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

Formats the value using the given formatter.

impl Error for TransportError

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<Error> for TransportError

fn from(source: Error) -> Self

Converts to this type from the input type.
