Struct CallStack 

pub struct CallStack { /* private fields */ }

Encapsulates a script call stack.

Implementations

impl CallStack

pub fn new() -> Self

Creates a new empty script call stack.

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

Removes the top from from the stack. If the stack is empty, does nothing and returns None; otherwise, returns the removed call frame.

pub fn push(&mut self, call_type: CallType, source: impl Into<String>)

Pushes a new frame onto the stack.

Arguments

• call_type - The type of script call (sourced or executed).
• source - The source of the script (e.g., file path).

pub fn in_sourced_script(&self) -> bool

Returns whether or not the current script stack frame is a sourced script.

pub fn depth(&self) -> usize

Returns the current depth of the script call stack.

pub fn is_empty(&self) -> bool

Returns whether or not the script call stack is empty.

pub fn iter(&self) -> impl Iterator<Item = &CallFrame>

Returns an iterator over the script call frames, starting from the most recent.
