Trait 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() -> [u8; 4] { ... }
}

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>

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() -> [u8; 4]

The selector of the error

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
