Struct ScopeTracker 

pub struct ScopeTracker { /* private fields */ }

Tracks variable bindings across nested scopes.

Unlike the interpreter’s Scope which holds values, this only tracks names for static validation purposes.

Implementations

impl ScopeTracker

pub fn new() -> Self

Create a new scope tracker with built-in special variables.

pub fn push_frame(&mut self)

Push a new scope frame.

Variables bound after this call are local to the new frame until pop_frame is called.

pub fn pop_frame(&mut self)

Pop the current scope frame.

Variables bound in this frame are forgotten. Panics if trying to pop the global frame.

pub fn bind(&mut self, name: impl Into<String>)

Bind a variable name in the current scope.

pub fn is_bound(&self, name: &str) -> bool

Check if a variable is bound in any scope.

Searches from innermost to outermost scope.

pub fn should_skip_undefined_check(name: &str) -> bool

Check if a variable name should skip undefined warnings.

Variables starting with underscore are conventionally external or intentionally unchecked.

pub fn depth(&self) -> usize

Get the current nesting depth.

Trait Implementations

fn default() -> Self

Returns the “default value” for a type.
