Trait ethers_contract::EthError

pub trait EthError: Tokenizable + AbiDecode + AbiEncode + Send + Sync {
    // Required methods
    fn error_name() -> Cow<'static, str>;
    fn abi_signature() -> Cow<'static, str>;

    // Provided methods
    fn from_rpc_response(response: &JsonRpcError) -> Option<Self> { ... }
    fn decode_with_selector(data: &[u8]) -> Option<Self> { ... }
    fn selector() -> Selector { ... }
}

A helper trait for types that represents a custom error type

Required Methods

fn error_name() -> Cow<'static, str>

The name of the error

fn abi_signature() -> Cow<'static, str>

Retrieves the ABI signature for the error

Provided Methods

fn from_rpc_response(response: &JsonRpcError) -> Option<Self>

Available on crate feature providers only.

Attempt to decode from a JsonRpcError by extracting revert data

Fails if the error is not a revert, or decoding fails

fn decode_with_selector(data: &[u8]) -> Option<Self>

Decode the error from EVM revert data including an Error selector

fn selector() -> Selector

The selector of the error

Object Safety

This trait is not object safe.
