Enum ExecError 

#[repr(u8)]
pub enum ExecError {
    InvalidInstance = 1,
    InvalidImage = 2,
    OutOfGas = 3,
    Trap = 4,
}

Errors that can be emitted when executing a new virtualization instance.

Variants

InvalidInstance = 1

The supplied instance_id was invalid or the instance was destroyed.

This error will also be returned if a recursive call into the same instance is attempted.

InvalidImage = 2

The supplied code was invalid. Most likely caused by invalid entry points.

OutOfGas = 3

The execution ran out of gas before it could finish.

Trap = 4

The execution trapped before it could finish.

This can be caused by executing an unimp instruction.

Trait Implementations

impl Debug for ExecError

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

Formats the value using the given formatter.

impl Decode for ExecError

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy, ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Encode for ExecError

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl From<ExecError> for u8

fn from(enum_value: ExecError) -> Self

Converts to this type from the input type.

impl PartialEq for ExecError

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

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

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

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

impl TryFrom<u8> for ExecError

type Error = TryFromPrimitiveError<ExecError>

The type returned in the event of a conversion error.

fn try_from(number: u8) -> Result<Self, TryFromPrimitiveError<Self>>

Performs the conversion.

impl TryFromPrimitive for ExecError

const NAME: &'static str = "ExecError"

type Primitive = u8

type Error = TryFromPrimitiveError<ExecError>

fn try_from_primitive( number: Self::Primitive, ) -> Result<Self, TryFromPrimitiveError<Self>>
