Enum BackendError

#[non_exhaustive]
pub enum BackendError {
    ForeignPanic {},
    BadArgument {},
    InvalidUtf8 {},
    IteratorDoesNotExist {
        id: u32,
    },
    OutOfGas {},
    Unknown {
        msg: String,
    },
    UserErr {
        msg: String,
    },
}

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.

Trait Implementations

impl Debug for BackendError

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

Formats the value using the given formatter.

impl Display for BackendError

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

Formats the value using the given formatter.

impl Error for BackendError

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<BackendError> for VmError

fn from(original: BackendError) -> Self

Converts to this type from the input type.

impl From<FromUtf8Error> for BackendError

fn from(_original: FromUtf8Error) -> Self

Converts to this type from the input type.

impl PartialEq for BackendError

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

Tests for self and other values to be equal, and is used by ==.

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

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