Expand description

An Error which is thrown when interacting with a smart contract

Variants§

§

DecodingError(Error)

Thrown when the ABI decoding fails

§

AbiError(AbiError)

Thrown when the internal BaseContract errors

§

DetokenizationError(InvalidOutputType)

Thrown when detokenizing an argument

§

MiddlewareError

Fields

§e: M::Error

The underlying error

Thrown when a middleware call fails

§

ProviderError

Fields

§e: ProviderError

The underlying error

Thrown when a provider call fails

§

Revert(Bytes)

Contract reverted

§

ConstructorError

Thrown during deployment if a constructor argument was passed in the deploy call but a constructor was not present in the ABI

§

ContractNotDeployed

Thrown if a contract address is not found in the deployment transaction’s receipt

Implementations§

source§

impl<M: Middleware> ContractError<M>

source

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

If this ContractError 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 ContractError::decode_revert

source

pub fn is_revert(&self) -> bool

True if the error is a revert, false otherwise

source

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

source

pub fn decode_contract_revert<Err: ContractRevert>(&self) -> Option<Err>

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

This is intended to be used with error enum outputs from abigen! contracts

source

pub fn from_middleware_error(e: M::Error) -> Self

Convert a MiddlewareError to a ContractError

source

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

Convert a ContractError to a MiddlewareError if possible.

source

pub fn is_middleware_error(&self) -> bool

True if the error is a middleware error

source

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

Convert a ContractError to a ProviderError if possible.

source

pub fn is_provider_error(&self) -> bool

True if the error is a provider error
