Struct CallStack 

pub struct CallStack { /* private fields */ }

Encapsulates a function call stack.

Implementations

impl CallStack

pub fn new() -> Self

Creates a new empty function call stack.

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

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, name: impl Into<String>, function_def: &Arc<FunctionDefinition>, )

Pushes a new frame onto the stack.

Arguments

• name - The name of the function being called.
• function_def - The definition of the function being called.

pub fn depth(&self) -> usize

Returns the current depth of the function call stack.

pub fn is_empty(&self) -> bool

Returns whether or not the function call stack is empty.

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

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