Enum StorageFetchError 

pub enum StorageFetchError {
    Runtime(RuntimeError),
    Provider {
        operation: &'static str,
        details: String,
    },
    Serialization {
        details: String,
    },
    BatchSend {
        details: String,
    },
    Custom {
        message: String,
    },
}

Error returned by storage/proof batch callbacks.

Clone lets a batch-level failure (one eth_call or one JSON-RPC batch) be reported once per affected slot without re-stringifying the source.

Variants

Runtime(RuntimeError)

Runtime precondition failure before a fetch could be made.

Provider

The provider rejected or failed an RPC request.

Fields

operation: &'static str

JSON-RPC method or high-level operation name.

details: String

Provider/transport error text. Alloy’s provider error type is generic over the transport, so this boundary preserves it as display text.

Serialization

JSON-RPC batch serialization failed before sending.

Fields

details: String

Serialization error text.

BatchSend

Sending the JSON-RPC batch failed before per-call waiters could resolve.

Fields

details: String

Send error text.

Custom

Caller-provided callback failure.

Fields

message: String

Caller-provided error text.

Implementations

impl StorageFetchError

pub fn provider(operation: &'static str, source: impl Display) -> Self

Build a provider-failure error from any displayable provider error.

pub fn batch_send(source: impl Display) -> Self

Build a batch-send error.

pub fn serialization(source: impl Display) -> Self

Build a serialization error.

pub fn custom(message: impl Into<String>) -> Self

Build a custom-callback error.

Trait Implementations

impl Clone for StorageFetchError

fn clone(&self) -> StorageFetchError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StorageFetchError

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

Formats the value using the given formatter.

impl Display for StorageFetchError

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

Formats the value using the given formatter.

impl Error for StorageFetchError

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<RuntimeError> for StorageFetchError

fn from(source: RuntimeError) -> Self

Converts to this type from the input type.
