Struct JsonRpcError

pub struct JsonRpcError {
    pub code: i64,
    pub message: String,
    pub data: Option<Value>,
}

A JSON-RPC 2.0 error

Fields

code: i64

message: String

The error message

data: Option<Value>

Additional data

Implementations

impl JsonRpcError

pub fn is_revert(&self) -> bool

Determine if the error output of the eth_call RPC request is a revert

Note that this may return false positives if called on an error from other RPC requests

pub fn as_revert_data(&self) -> Option<Bytes>

Attempt to extract revert data from the JsonRpcError be recursively traversing the error’s data field

This returns the first hex it finds in the data object, and its behavior may change with serde_json internal changes.

If no hex object is found, it will return an empty bytes IFF the error is a revert

Inspired by ethers-js logic: https://github.com/ethers-io/ethers.js/blob/9f990c57f0486728902d4b8e049536f2bb3487ee/packages/providers/src.ts/json-rpc-provider.ts#L25-L53

pub fn decode_revert_data<E>(&self) -> Option<E>

where E: AbiDecode,

Decode revert data (if any) into a decodeable type

Trait Implementations

impl Clone for JsonRpcError

fn clone(&self) -> JsonRpcError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JsonRpcError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for JsonRpcError

fn deserialize<__D>( __deserializer: __D, ) -> Result<JsonRpcError, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for JsonRpcError

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

Formats the value using the given formatter.

impl Error for JsonRpcError

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.
