Custom error type for contract-related errors

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidNeoName(String)

Error indicating an invalid Neo name

InvalidNeoNameServiceRoot(String)

Error indicating an invalid Neo Name Service root

UnexpectedReturnType(String)

Error indicating an unexpected return type

UnresolvableDomainName(String)

Error indicating an unresolvable domain name

DomainNameNotAvailable(String)

Error indicating that a domain name is not available

DomainNameNotRegistered(String)

Error indicating that a domain name is not registered

UnsupportedOperation(String)

Error indicating an unsupported operation

RuntimeError(String)

Error indicating a runtime error

InvalidStateError(String)

Error indicating an invalid state error

InvalidArgError(String)

Error indicating an invalid argument error

ProviderError(ProviderError)

Error indicating a provider error, transparently wrapped

ProviderNotSet(String)

Error indicating that a provider is not set

InvocationFailed(String)

Error indicating that an invocation failed

InvalidResponse(String)

Error indicating an invalid response

InvalidAccount(String)

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)>

Returns 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.

impl From<ContractError> for NeoError

fn from(err: ContractError) -> Self

Converts to this type from the input type.

impl From<ProviderError> for ContractError

fn from(source: ProviderError) -> Self

Converts to this type from the input type.
