Enum ethers_contract::ContractError

pub enum ContractError {
    DecodingError(AbiError),
    DetokenizationError(InvalidOutputType),
    ClientError(ClientError),
    ProviderError(ProviderError),
    ConstructorError,
    ContractNotDeployed,
}

An Error which is thrown when interacting with a smart contract

Variants

DecodingError(AbiError)

Thrown when the ABI decoding fails

DetokenizationError(InvalidOutputType)

Thrown when detokenizing an argument

ClientError(ClientError)

Thrown when a client call fails

ProviderError(ProviderError)

Thrown when a provider call fails

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

Trait Implementations

impl Debug for ContractError

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

Formats the value using the given formatter.

impl Display for ContractError

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

Formats the value using the given formatter.

impl Error for ContractError

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
