Enum RpcError 

pub enum RpcError {
    Arb(ArbError),
    BlockProducer(BlockProducerError),
    Provider(ProviderError),
    InvalidParams(String),
    Base64Decode(String),
    NotFound(String),
    Internal(String),
}

Errors surfaced by the Arbitrum RPC handlers.

Variants split user-input failures (mapped to -32602 invalid params) from internal failures (mapped to -32603 internal error, with the source redacted before serialization).

Variants

Arb(ArbError)

Failure originating in the wider arbreth error chain.

BlockProducer(BlockProducerError)

Block production failed downstream of the RPC entrypoint.

Provider(ProviderError)

State-provider lookup failed.

InvalidParams(String)

A required RPC parameter was missing or malformed.

Base64Decode(String)

A base64-encoded byte field could not be decoded.

NotFound(String)

A requested resource (block, header) was not found.

Internal(String)

Catch-all for transient internal failures that do not yet have a dedicated variant. Source is redacted on the wire.

Implementations

impl RpcError

pub fn invalid_params(msg: impl Display) -> Self

Construct an RpcError::InvalidParams from a displayable value.

pub fn base64_decode(msg: impl Display) -> Self

Construct an RpcError::Base64Decode from a displayable value.

pub fn not_found(msg: impl Display) -> Self

Construct an RpcError::NotFound from a displayable value.

pub fn internal(msg: impl Display) -> Self

Construct an RpcError::Internal from a displayable value.

Trait Implementations

impl Debug for RpcError

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

Formats the value using the given formatter.

impl Display for RpcError

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

Formats the value using the given formatter.

impl Error for RpcError

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.
