Enum sputnikvm::errors::OnChainError

pub enum OnChainError {
    StackOverflow,
    StackUnderflow,
    InvalidOpcode,
    BadJumpDest,
    PCOverflow,
    EmptyGas,
    InvalidRange,
    NotStatic,
    Revert,
}

Errors that can be written on chain.

Variants

StackOverflow

Stack is overflowed (pushed more than 1024 items to the stack).

StackUnderflow

Stack is underflowed (poped an empty stack).

InvalidOpcode

The opcode is invalid and the PC is not able to convert it to an instruction.

BadJumpDest

PC jumped to an invalid jump destination.

PCOverflow

PC overflowed (tries to read the next opcode which is already the end of the code). In Yellow Paper, this is categorized the same as InvalidOpcode.

EmptyGas

Not enough gas to continue.

InvalidRange

For instruction that requires reading a range, it is invalid. This in the Yellow Paper is covered by EmptyGas.

NotStatic

In static context but does mutation.

Revert

Invoked by REVERT opcode.

Trait Implementations

impl Clone for OnChainError

fn clone(&self) -> OnChainError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OnChainError

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

Formats the value using the given formatter.

impl From<OnChainError> for EvalError

fn from(val: OnChainError) -> EvalError

Converts to this type from the input type.

impl From<OnChainError> for EvalOnChainError

fn from(val: OnChainError) -> EvalOnChainError

Converts to this type from the input type.

impl From<OnChainError> for RuntimeError

fn from(val: OnChainError) -> RuntimeError

Converts to this type from the input type.

impl PartialEq<OnChainError> for OnChainError

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

This method tests for self and other values to be equal, and is used by ==.

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

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