Struct StackFrame 

pub struct StackFrame {
    pub function: String,
    pub locals: Vec<(String, u64)>,
    pub return_address: usize,
}

A simulated stack frame for explicit-stack recursion.

Fields

function: String

The function name at this frame.

locals: Vec<(String, u64)>

Local variable bindings as (name, value) pairs.

return_address: usize

The return address (index into a bytecode chunk).

Implementations

impl StackFrame

pub fn new(function: &str, return_address: usize) -> Self

Create a new stack frame.

pub fn bind(&mut self, name: &str, value: u64)

Add a local variable binding.

pub fn lookup(&self, name: &str) -> Option<u64>

Look up a local variable by name.

Trait Implementations

impl Clone for StackFrame

fn clone(&self) -> StackFrame

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StackFrame

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