Enum Error 

#[non_exhaustive]
pub enum Error {
    Rpc(RpcError),
    Abi(AbiError),
    Config(ConfigError),
    Output(OutputError),
    Checkpoint(CheckpointError),
    Io(Error),
    Json(Error),
    Other(String),
}

Main error type for the library

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Rpc(RpcError)

RPC-related errors

Abi(AbiError)

ABI-related errors

Config(ConfigError)

Configuration errors

Output(OutputError)

Output errors

Checkpoint(CheckpointError)

Checkpoint errors

Io(Error)

Generic IO error

Json(Error)

JSON serialization error

Other(String)

Generic error for cases that don’t fit other categories.

When using this variant, prefer including context about the operation that failed, e.g., Error::Other(format!("Failed to parse address: {}", input)) rather than just passing through a raw error message.

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

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.

fn from(source: AbiError) -> Self

Converts to this type from the input type.

impl From<CheckpointError> for Error

fn from(source: CheckpointError) -> Self

Converts to this type from the input type.

impl From<ConfigError> for Error

impl RetryableError for Error

Implement RetryableError for the main Error type.

fn is_retryable(&self) -> bool

Returns true if the error is transient and the operation should be retried

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

Returns the retry-after duration if specified by the error
