Enum Outcome

pub enum Outcome {
    Halt,
    Panic,
    PageFault {
        page: u64,
        num_pages: u64,
    },
    OutOfGas,
    OutputLimitReached,
}

The result code returned by CoreVM service.

It is similar to InvokeOutcome but does not include host-call faults because they are automatically handled by CoreVM.

Variants

Halt

Completed normally.

Panic

Completed with a panic.

PageFault

Completed with a page fault that couldn’t be handled by CoreVM.

Undhandled page fault might occur because either the max. no. of exports is reached or the corresponding page was not imported by the work package. In the former case the program needs to be resumed in the next work package without any further action from the builder. In the latter case the page with the specified address has to be imported on the next program run to continue.

Fields

page: u64

num_pages: u64

OutOfGas

Completed by running out of gas.

OutputLimitReached

The inner VM has reached the max. no. of exports while appending new data to the output stream.

Trait Implementations

impl Clone for Outcome

fn clone(&self) -> Outcome

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Outcome

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

Formats the value using the given formatter.

impl Decode for Outcome

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 Outcome

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 MaxEncodedLen for Outcome

fn max_encoded_len() -> usize

Upper bound, in bytes, of the maximum encoded size of this item.

impl PartialEq for Outcome

fn eq(&self, other: &Outcome) -> 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.
