}

Function Stack

Fields

return_stack: Vec<FunctionReturnFrame>

current_code_idx: usize

Implementations

impl FunctionStack

pub fn new() -> Self

Returns new function stack.

pub fn push(&mut self, program_counter: usize, new_idx: usize)

Pushes a new frame to the stack. and sets current_code_idx to new value.

pub fn return_stack_len(&self) -> usize

Return stack length

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

Pops a frame from the stack and sets current_code_idx to the popped frame’s idx.

pub fn set_current_code_idx(&mut self, idx: usize)

Sets current_code_idx, this is needed for JUMPF opcode.

Trait Implementations

impl Clone for FunctionStack

fn clone(&self) -> FunctionStack

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionStack

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

Formats the value using the given formatter.

impl Default for FunctionStack

fn default() -> FunctionStack

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FunctionStack

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FunctionStack

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for FunctionStack

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
