Enum VMRunnerError

pub enum VMRunnerError {
    InconsistentStateError(InconsistentStateError),
    CacheError(CacheError),
    LoadingError(String),
    ExternalError(AnyError),
    Nondeterministic(String),
    WasmUnknownError {
        debug_message: String,
    },
}

For bugs in the runtime itself, crash and die is the usual response.

See the doc comment on VMResult for an explanation what the difference between this and a FunctionCallError is.

Variants

InconsistentStateError(InconsistentStateError)

An error that is caused by an operation on an inconsistent state. E.g. an integer overflow by using a value from the given context.

CacheError(CacheError)

Error caused by caching.

LoadingError(String)

Error (eg, resource exhausting) when loading a successfully compiled contract into executable memory.

ExternalError(AnyError)

Type erased error from External trait implementation.

Nondeterministic(String)

Non-deterministic error.

WasmUnknownError

Fields

debug_message: String

Trait Implementations

impl Debug for VMRunnerError

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

Formats the value using the given formatter.

impl Display for VMRunnerError

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

Formats the value using the given formatter.

impl Error for VMRunnerError

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<CacheError> for VMRunnerError

fn from(source: CacheError) -> Self

Converts to this type from the input type.
