Enum ethers_contract::MulticallError

pub enum MulticallError<M: Middleware> {
    ContractError(ContractError<M>),
    InvalidChainId(u64),
    IllegalRevert,
}

Available on crate features providers and abigen only.

Errors using the crate::Multicall system

Variants

ContractError(ContractError<M>)

Contract call returned an error

InvalidChainId(u64)

Unsupported chain

IllegalRevert

Contract call reverted when not allowed

Implementations

impl<M: Middleware> MulticallError<M>

pub fn as_contract_error(&self) -> Option<&ContractError<M>>

Convert a MulticallError to a the underlying error if possible.

pub fn is_contract_error(&self) -> bool

True if the underlying error is a ContractError

pub fn as_middleware_error(&self) -> Option<&M::Error>

Convert a MulticallError to a the underlying error if possible.

pub fn is_middleware_error(&self) -> bool

True if the underlying error is a MiddlewareError

pub fn as_provider_error(&self) -> Option<&ProviderError>

Convert a MulticallError to a ProviderError if possible.

pub fn is_provider_error(&self) -> bool

True if the error is a provider error

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

If this MulticallError is a revert, this method will retrieve a reference to the underlying revert data. This ABI-encoded data could be a String, or a custom Solidity error type.

Returns

None if the error is not a revert Some(data) with the revert data, if the error is a revert

Note

To skip this step, consider using MulticallError::decode_revert

pub fn is_revert(&self) -> bool

True if the error is a revert, false otherwise

pub fn decode_revert<Err: EthError>(&self) -> Option<Err>

Decode revert data into an EthError type. Returns None if decoding fails, or if this is not a revert

Trait Implementations

impl<M: Debug + Middleware> Debug for MulticallError<M>

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

Formats the value using the given formatter.

impl<M: Middleware> Display for MulticallError<M>

where ContractError<M>: Display,

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

Formats the value using the given formatter.

impl<M: Middleware> Error for MulticallError<M>

where ContractError<M>: Error, Self: Debug + Display,

fn source(&self) -> Option<&(dyn Error + 'static)>

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.
