Enum Error 

pub enum Error {
    Timeout,
    RpcError(RpcError<TransportErrorKind>),
    BlockNotFound,
    Closed,
    Lagged(u64),
}

Errors that can occur when using super::RobustProvider.

Variants

Timeout

The operation exceeded the configured timeout.

RpcError(RpcError<TransportErrorKind>)

An RPC error occurred after exhausting all retry attempts.

BlockNotFound

The requested block was not found.

This error is returned when the underlying provider returns None for the requested block, or when detecting client-specific RPC error responses that indicate a missing block (e.g., Geth’s error code -32000 with a “block … not found”-like message).

Note: This classification has been verified on Anvil, Reth, and Geth. Other clients may use different error codes/messages; in those cases the error may surface as Error::RpcError.

Closed

The subscription channel was closed.

Lagged(u64)

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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
