pub enum ExecutionError {
    Web3(Web3Error),

    Parse(ParseIntError),
    NoLocalAccounts,
    Revert(Option<String>),

}

Error that can occur while executing a contract call or transaction.

Variants

Web3(Web3Error)

An error occured while performing a web3 call.

AbiDecode(Web3ContractError)

An error occured while ABI decoding the result of a contract method call.

Parse(ParseIntError)

An error occured while parsing chain ID received from a Web3 call.

NoLocalAccounts

An error indicating that an attempt was made to build or send a locally signed transaction to a node without any local accounts.

Revert(Option<String>)

A contract call reverted.

InvalidOpcode

A contract call executed an invalid opcode.

ConfirmTimeout

A contract transaction failed to confirm within the block timeout limit.

Failure(Box<TransactionReceipt>)

Transaction failure (e.g. out of gas or revert).

UnsupportedToken

A call returned an unsupported token. This happens when using the experimental ABIEncoderV2 option.

This is intended to be implemented in future version of ethcontract.

MissingTransaction(H256)

Failed to find a transaction by hash.

PendingTransaction(H256)

Failed to get a block for a pending transaction that has not yet been mined.

Trait Implementations

impl Debug for ExecutionError

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

Formats the value using the given formatter.

impl Display for ExecutionError

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

Formats the value using the given formatter.

impl Error for ExecutionError

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
