[−][src]Struct evm::Stack
Represents an EVM stack.
Methods
impl Stack
[src]
impl Stack
pub fn check_pop_push( | [src] |
Check a pop-push cycle. If the check succeeded, push
, pop
,
set
, peek
within the limit should not fail.
pub fn push(&mut self, elem: M256) -> Result<(), OnChainError> | [src] |
Push a new value to the stack.
pub fn pop(&mut self) -> Result<M256, OnChainError> | [src] |
Pop a value from the stack.
pub fn set(&mut self, no_from_top: usize, val: M256) -> Result<(), OnChainError> | [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.
pub fn peek(&self, no_from_top: usize) -> Result<M256, OnChainError> | [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 len(&self) -> usize | [src] |
Get the current stack length.
pub fn is_empty(&self) -> bool | [src] |
Returns true if stack is empty
