Enum TransportError 

pub enum TransportError {
    Grpc(Status),
}

Transport error type.

Variants

Grpc(Status)

gRPC error

Implementations

impl TransportError

pub fn is_proxy_failure(&self) -> bool

Whether the request failed because the SOCKS5 proxy failed rather than the node (a ProxyError is in the error’s source chain). Such a failure says nothing about the node, so it is neither retried nor held against it.

Trait Implementations

impl CanRetry for TransportError

fn can_retry(&self) -> bool

Returns true if the operation can be retried safely.

fn rate_limit_ban_duration(&self) -> Option<Duration>

If this error is a gRPC ResourceExhausted (Envoy rate-limit) that carries a RateLimit-Reset metadata header, returns the server-advertised ban duration (clamped to a safe range). Returns None for all other errors and for rate-limit errors that carry no usable header (the caller falls back to the normal exponential ban ladder in that case).

fn is_no_available_addresses(&self) -> bool

Returns true if this error represents a “no available addresses” condition.

fn is_node_failure(&self) -> bool

👎Deprecated:

Use !can_retry() instead

Get boolean flag that indicates if the error is retryable.

impl Clone for TransportError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TransportError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TransportError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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<Status> for TransportError

fn from(source: Status) -> Self

Converts to this type from the input type.

impl Mockable for TransportError

Serialization of TransportError.

We need to do manual serialization because of the generic type parameter which doesn’t support serde derive.

fn mock_serialize(&self) -> Option<Vec<u8>>

Serialize the message to bytes for mocking purposes.

fn mock_deserialize(data: &[u8]) -> Option<Self>

Deserialize the message serialized with [mock_serialize()].

impl Mockable for Box<TransportError>

Serialization of boxed TransportError.

fn mock_serialize(&self) -> Option<Vec<u8>>

Serialize the message to bytes for mocking purposes.

fn mock_deserialize(data: &[u8]) -> Option<Self>

Deserialize the message serialized with [mock_serialize()].

impl Serialize for TransportError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
