Fields

instruction_pointer: *const u8

Instruction pointer.

instruction_result: InstructionResult

Return is main control flag, it tell us if we should continue interpreter or break from it

gas: Gas

left gas. Memory gas can be found in Memory field.

memory: Memory

Memory.

stack: Stack

Stack.

return_data_buffer: Bytes

After call returns, its return data is saved here.

return_range: Range<usize>

Return value.

is_static: bool

Is interpreter call static.

contract: Contract

Contract information and invoking data

Implementations

impl Interpreter

pub fn current_opcode(&self) -> u8

Current opcode

pub fn new(contract: Contract, gas_limit: u64, is_static: bool) -> Self

Create new interpreter

pub fn contract(&self) -> &Contract

pub fn gas(&self) -> &Gas

pub fn memory(&self) -> &Memory

Reference of interpreter memory.

pub fn stack(&self) -> &Stack

Reference of interpreter stack.

pub fn add_next_gas_block(&mut self, pc: usize) -> Option<InstructionResult>

pub fn program_counter(&self) -> usize

Return a reference of the program counter.

pub fn step<H: Host, SPEC: Spec>(&mut self, host: &mut H)

Execute next instruction

pub fn run<H: Host, SPEC: Spec>(&mut self, host: &mut H) -> InstructionResult

loop steps until we are finished with execution

pub fn run_inspect<H: Host, SPEC: Spec>(
    &mut self,
    host: &mut H
) -> InstructionResult

loop steps until we are finished with execution

pub fn return_value(&self) -> Bytes

Copy and get the return value of the interpreter, if any.
