Enum 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.
