Struct Machine

pub struct Machine<S> {
    pub retval: Vec<u8>,
    pub memory: Memory,
    pub stack: Stack,
    pub state: S,
    /* private fields */
}

Core execution layer for EVM.

Fields

retval: Vec<u8>

Return value. Note the difference between retbuf. A retval holds what’s returned by the current machine, with RETURN or REVERT opcode. A retbuf holds the buffer of returned value by sub-calls.

memory: Memory

Memory.

stack: Stack

Stack.

state: S

Extra state,

Implementations

impl<S> Machine<S>

pub fn new( code: Rc<Vec<u8>>, data: Rc<Vec<u8>>, stack_limit: usize, memory_limit: usize, state: S, ) -> Self

Create a new machine with given code and data.

pub fn code(&self) -> &[u8]

Machine code.

pub fn is_empty(&self) -> bool

Whether the machine has empty code.

Trait Implementations

impl<'etable, S, ES> AsMut<Machine<S>> for EtableInterpreter<'etable, S, ES>

fn as_mut(&mut self) -> &mut Machine<S>

Converts this type into a mutable reference of the (usually inferred) input type.

impl<'etable, S, ES> AsRef<Machine<S>> for EtableInterpreter<'etable, S, ES>

fn as_ref(&self) -> &Machine<S>

Converts this type into a shared reference of the (usually inferred) input type.
