Error type for node queries.

This error is meant to be serialized over the network and aggregated by clients (i.e. clients will track validator votes on each error value).

Implementations

impl NodeError

pub fn parse_invalid_timestamp(&self) -> Option<InvalidTimestampError>

If this error is an InvalidTimestamp error (wrapped in WorkerError), parses and returns the timestamps. Returns None for other error types.

The error string format is expected to contain [us:{block_timestamp}:{local_time}] where both values are microseconds since epoch.

impl NodeError

pub fn is_expected(&self) -> bool

Returns whether this error is an expected part of the protocol flow.

Expected errors are those that validators return during normal operation and that the client handles automatically (e.g. by supplying missing data and retrying). Unexpected errors indicate genuine network issues, validator misbehavior, or internal problems.

Trait Implementations

impl Clone for NodeError

fn clone(&self) -> NodeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NodeError

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for NodeError

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

Formats the value using the given formatter.

impl Error for NodeError

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<ArithmeticError> for NodeError

fn from(error: ArithmeticError) -> Self

Converts to this type from the input type.

impl From<ChainError> for NodeError

fn from(error: ChainError) -> Self

Converts to this type from the input type.

impl From<CryptoError> for NodeError

fn from(error: CryptoError) -> Self

Converts to this type from the input type.

impl From<NodeError> for ChainClientError

fn from(source: NodeError) -> Self

Converts to this type from the input type.

impl From<Status> for NodeError

fn from(status: Status) -> Self

Converts to this type from the input type.

impl From<ViewError> for NodeError

fn from(error: ViewError) -> Self

Converts to this type from the input type.

impl From<WorkerError> for NodeError

fn from(error: WorkerError) -> Self

Converts to this type from the input type.

impl Hash for NodeError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for NodeError

fn eq(&self, other: &NodeError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for NodeError

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
