Struct evm::Stack[][src]

pub struct Stack { /* fields omitted */ }

EVM stack.

Implementations

impl Stack[src]

pub fn new(limit: usize) -> Stack[src]

Create a new stack with given limit.

pub fn limit(&self) -> usize[src]

Stack limit.

pub fn len(&self) -> usize[src]

Stack length.

pub fn pop(&mut self) -> Result<H256, ExitError>[src]

Pop a value from the stack. If the stack is already empty, returns the StackUnderflow error.

pub fn push(&mut self, value: H256) -> Result<(), ExitError>[src]

Push a new value into the stack. If it will exceed the stack limit, returns StackOverflow error and leaves the stack unchanged.

pub fn peek(&self, no_from_top: usize) -> Result<H256, ExitError>[src]

Peek a value at given index for the stack, where the top of the stack is at index 0. If the index is too large, StackError::Underflow is returned.

pub fn set(&mut self, no_from_top: usize, val: H256) -> Result<(), ExitError>[src]

Set a value at given index for the stack, where the top of the stack is at index 0. If the index is too large, StackError::Underflow is returned.
