Enum sp_state_machine::ExecutionError

pub enum ExecutionError {
    Backend(DefaultError),
    CodeEntryDoesNotExist,
    UnableToGenerateProof,
    InvalidProof,
}

Externalities Error.

Externalities are not really allowed to have errors, since it’s assumed that dependent code would not be executed unless externalities were available. This is included for completeness, and as a transition away from the pre-existing framework.

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 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, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl PartialEq<ExecutionError> for ExecutionError

fn eq(&self, other: &ExecutionError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
