[−][src]Struct evm::PC
Represents a program counter in EVM.
Methods
impl<'a, P: Patch> PC<'a, P>[src]
pub fn code(&self) -> &[u8][src]
Get the code bytearray.
pub fn position(&self) -> usize[src]
Get the current program counter position.
pub fn opcode_position(&self) -> usize[src]
Get the current opcode position. Should only be used when debugging.
pub fn is_valid(&self, position: usize) -> bool[src]
Returns true if the position is a valid jump destination. If
not, returns false.
pub fn is_end(&self) -> bool[src]
Check whether the PC is ended. Next read on this PC would
result in PCError::PCOverflow.
pub fn peek_opcode(&self) -> Result<Opcode, OnChainError>[src]
Peek the next opcode.
pub fn peek(&self) -> Result<Instruction, OnChainError>[src]
Peek the next instruction.
impl<'a, P: Patch> PC<'a, P>[src]
pub fn new(
patch: &'a P,
code: &'a [u8],
valids: &'a Valids,
position: &'a usize
) -> Self[src]
patch: &'a P,
code: &'a [u8],
valids: &'a Valids,
position: &'a usize
) -> Self
Create a new program counter from the given code.
