Struct tari_crypto::script::ExecutionStack

pub struct ExecutionStack { /* fields omitted */ }

Implementations

impl ExecutionStack

pub fn new(items: Vec<StackItem>) -> Self

Return a new ExecutionStack using the vector of StackItem in items

pub fn size(&self) -> usize

Returns the number of entries in the execution stack

pub fn peek(&self) -> Option<&StackItem>

Returns a reference to the top entry in the stack without affecting the stack

pub fn is_empty(&self) -> bool

Returns true if the stack is empty

pub fn pop(&mut self) -> Option<StackItem>

Pops the top item in the stack. If the stack is not empty, pop returns the item, otherwise return None if it is empty.

pub fn as_bytes(&self) -> Vec<u8>

Return a binary array representation of the input stack

pub fn from_bytes(bytes: &[u8]) -> Result<Self, ScriptError>

pub fn push(&mut self, item: StackItem) -> Result<(), ScriptError>

Pushes the item onto the top of the stack. This function will only error if the new stack size exceeds the maximum allowed stack size, given by [MAX_STACK_SIZE]

Trait Implementations

impl Clone for ExecutionStack

fn clone(&self) -> ExecutionStack

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExecutionStack

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ExecutionStack

fn default() -> ExecutionStack

Returns the "default value" for a type.

impl Eq for ExecutionStack

impl Hex for ExecutionStack

fn from_hex(hex: &str) -> Result<Self, HexError> where
    Self: Sized, 

Try to convert the given hexadecimal string to the type. Any failures (incorrect string length, non hex characters, etc) return a KeyError with an explanatory note.

fn to_hex(&self) -> String

Return the hexadecimal string representation of the type

impl PartialEq<ExecutionStack> for ExecutionStack

fn eq(&self, other: &ExecutionStack) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &ExecutionStack) -> bool

This method tests for !=.
