Implementations

impl<T> VmResult<T>

pub fn panic<D>(message: D) -> Self

where D: 'static + BoxedPanic,

Construct a result containing a panic.

pub fn expected<E>(actual: TypeInfo) -> Self

where E: ?Sized + TypeOf,

Construct an expectation error. The actual type received is actual, but we expected E.

pub fn is_ok(&self) -> bool

Test if the result is an ok.

pub fn is_err(&self) -> bool

Test if the result is an error.

pub fn expect(self, msg: &str) -> T

Expect a value or panic.

pub fn unwrap(self) -> T

Unwrap the interior value.

pub fn into_result(self) -> Result<T, VmError>

Convert a VmResult into a Result.

pub fn err<E>(error: E) -> Self

where VmError: From<E>,

Construct a new error from a type that can be converted into a VmError.
